Abstract

Background: Digital Pathology (DP) and Artificial Intelligence (AI) have strongly developed in recent years, especially in pathology, with a high interest in dermatopathology. Accelerated by the COVID-19 pandemic, DP and AI are now integrated in pathology, research and education, bringing value to histopathological diagnoses, telepathology and personalized medicine. This narrative review presents a comprehensive literature review by defining three research directions, using scientometric analysis, of the current state of DP and AI in pathology and dermatopathology. Methods: The research was conducted through the Pubmed and Web of Science databases, within the research period of January 2019–July 2025: a two-phase methodology. Four independent pathologists selected the articles in accordance with the inclusion and exclusion criteria, and the synthesis of the articles was based on three research directions. Results: The research shows that CNN (Convolutional Neural Network), AI powered diagnostic platforms and telepathology strongly contribute to increasing the speed and accuracy of diagnostics, especially on cutaneous malignant skin tumors. There are still several challenges and limitations in terms of validation, interoperability, initial high implementation costs, ethics and transparency in AI and equity in healthcare. Conclusions: DP and AI are essential pillars of modern dermatopathology, with a high necessity of standardization, regulation and a multidisciplinary approach.

1. Introduction

The last decade has been a hallmark for digital transformation in many fields, including healthcare. Pathology is one of the healthcare domains in which digital transformation, by developing Digital Pathology (DP) and Artificial Intelligence (AI) and integrating them into histopathological diagnoses, has undergone tremendous development. What was once considered innovative or experimental is nowadays integrated into daily clinical practice, research or teaching [1,2,3,4]. The accuracy of histopathological diagnoses, via the combination of Whole Slide Imaging (WSI), computational pathology and automated learning algorithms has increased alongside the development of technology. It is not only about the diagnoses, but also the redefinition of personalized medicine, with a strong focus on classifying aggressive cutaneous tumors, such as melanoma [5,6,7,8].
AI in healthcare has many applications, such as radiology, pathology and pharmacology. Also, AI is a real help in infectious diseases for the rapid identification of pathogens and epidemiological monitorization. Besides this, personalized decision making via the integration of clinical, pathological, imagistic and molecular data can be carried out using AI [9].
DP has constantly evolved since the first applications of telepathology in 1960 and upon the development and integration of AI, and is starting to be a technology with a high grade of maturity, being used in more laboratories across the world [10]. As DP is constantly evolving, it can emerge in daily activities like slide archival, in-line scanning, remote consultation and telepathology, tumor boards, education and research [11].
The progress in DP and AI, especially with the use of CNNs, has evolved tremendously in recent years, especially in dermatopathology, where assisted-AI tools are helping pathologists to establish advanced and more accurate diagnoses for skin lesions [12]. Dermatopathology is not the only field of pathology in which AI is evolving. Prostate cancer can be detected and graded through AI software and further research is being conducted on its predictive and prognostic predictions [13].
The COVID-19 pandemic has worked exactly like a catalyst for developing DP [14]. With an increased lack of access to medical services for patients, social distance regulations and the necessity of readapting all workflows, the COVID-19 pandemic accelerated the development of digital services. Because of this, DP became an essential component of maintaining the quality of histopathological diagnostics, opening the doors to worldwide medical expertise [15,16,17]. In parallel, AI has rapidly developed, with capacities of interpreting WSI and identifying regions of interest (ROI) and the ability to generate preliminary histopathological reports, with a high interest in dermatopathology [18,19].
The aim of this review is to provide a comprehensive analysis of the current state of DP and AI in dermatopathology, with a highlight on technological achievements, clinical implications, regulatory advice, perspectives and limitations in implementing DP and AI in dermatopathology through a scientometric approach, and a definition of the most recent research directions in the field. By using this approach, this review is the first of its kind in the literature at the moment of submission.

2. Methodology

The present review is a narrative review based on comprehensive literature research in two major biomedical databases (Web of Science and Pubmed) for articles and reviews regarding DP and AI in dermatopathology. The research process was performed in March–July 2025 and included articles published between January 2019 and July 2025. The methodology used for the review was divided into two phases.
Phase one was conducted through a scientometric study on Web of Science to establish the research directions. The research started with the research query for interrogation of the Web of Science database presented in Figure 1.
After the research was performed through Web of Science, inclusion and exclusion criteria were used to include articles in the defining research direction process as shown in the Figure 2. Beside the included articles from the research performed, several articles were included for the relevance of the review (AI in pathology, DP in pathology, IVD, etc.) from other databases (Figure 2).
Through the extracted 59 articles from the Web of Science database [4,12,20,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35,36,37,38,39,40,41,42,43,44,45,46,47,48,49,50,51,52,53,54,55,56,57,58,59,60,61,62,63,64,65,66,67,68,69,70,71,72,73,74,75], we have performed a scientometric analysis based on the keywords used in the abstract of every article. For this, we used the VOSviewer software (version 1.6.20, released on 31 October 2023) [76] to extract the keywords from each article, the relations between them and to generate the scientometric maps and the density maps. A total of 289 keywords were included in the scientometric analysis, with a minimum threshold of three occurrences of the keywords in the selected articles. Using this threshold, a total of 36 keywords were included for the scientometric cartographies based on their co-occurrences and the total link strength. After processing through VOSviewer, based on the scientometric map generated (Figure 3) and the density map of keywords (Figure 4), three clusters of keywords were generated based on co-occurrences and connections between them, as shown in Figure 5.
Based on these three clusters we established the three research directions for digital pathology and artificial intelligence in dermatopathology, as shown in Figure 6.
Phase two was the review of the articles included in the study. As shown in Figure 2, besides the articles included to establish the research directions, several articles were included for consistency and relevance. The selection of articles was made by four independent reviewers (pathologists) who underwent a screening process for all articles. A total of 109 articles met all the inclusion criteria and were included in the study. No patients or patient data were used for this review.

3. Research Direction 1—Advanced Algorithms and Artificial Intelligence for Diagnosis in Dermatopathology

Artificial intelligence is nowadays considered by pathologists to be a valuable partner. As AI is continuously developing, AI algorithms can pre-screen the slides, highlighting the interest zones or even providing a preliminary interpretation (Figure 7). AI is already being used in dermatopathology for the classification of tumoral lesions and the detection of melanocytic pathologies [77,78].
Artificial intelligence (AI) has developed rapidly and is emerging in every field, with a special interest in healthcare. In pathology, AI is allowing for the integration of histopathological, molecular and clinical data, resulting in a strong point for personalized medicine by identifying therapeutical biomarkers and establishing a degree of risk classification, including aggressive tumors in dermatopathology, like melanoma [77].
The integration of AI into different platforms and cloud systems may represent a real help and offer diagnostic services in regions where there is a lack of dermatopathologists, and by this, contribute to the decrease in imbalance in healthcare equity throughout the world [48,79].
By integrating AI into dermatopathology, a series of transversal benefits like stratification and diagnostic accuracy, prediction of treatment response and medical education may be the source of revolution in the domain [77]. The integration of AI into dermatopathology has the support of the worldwide medical community, with a high percentage of consensus for increasing diagnostic efficiency and accuracy, with 84.1% of dermatopathology specialists believing that AI should be included in medical education [26]. Progress in integrating AI depends on a multidisciplinary approach, with strong collaboration between dermatologists, other clinicians, bioinformatics and engineers. An important aspect is the importance that is given to the doctor–patient relationship and the decision-making responsibilities that can be adjusted with AI [29,51,80].
Emerging AI technologies, like Generative AI (which can generate rare histopathological images) and federated learning (which may train models without affecting the confidentiality of the data) go beyond the educational and diagnostic roles of AI, increasing the confidentiality levels and reducing ethical concerns, therefore increasing the quality of generative models [77].
Standardization is the most important fact that needs to be taken into consideration while advancing AI in dermatopathology. Firstly, the automatization of repetitive tasks, such as excision margins evaluation or the mitotic figures count can be implemented to standardize the process and further concentrate the resources of the lab for more complex cases [77]. Optimization and standardization through the reporting system must be taken into consideration. Multiple AI software, like ReportTutor [81], use a natural language model to help doctors to generate diagnostic reports which are in accordance with reality, promoting standardization into medical practice. HistoGPT (Helmholtz Munich, 2025, Germany) [82] is also a generative AI integration tool for generating pathology reports from images and thereby leading to future standardization.
Deep learning algorithms, especially convolutional neural networks (CNNs) have demonstrated an accuracy of 95% in diagnostics in dermatopathology [48,77,78,83]. CNNs can now be applied to WSI and thereby process digital images, with a component of assisted or independent diagnostics, reducing the time needed for dermatopathology diagnostics. Interobserver variability may be reduced when diagnosing basal cell carcinoma or melanoma. Machine learning (ML) algorithms like Fast Random Forest can also reduce interobserver variability, for example regarding the differences between dysplastic nevi and melanoma [29].
ResNet and VGG-19 (Visual Geometry Group, University of Oxford, 2014, Oxford, UK) models which were trained on over 9.95 million histological patches from WSI, have demonstrated a superior accuracy in differentiating melanocytic nevi from melanoma [80,84]. PDLS (Pathology Deep Learning Systems) are using CNNs on multiple levels like image adaptation, identifying the region of interest and final classification with trust scores. This multistep approach is increasing the confidence level in comparison to classic approaches [20]. AutoML can facilitate the integration of AI models without advanced technical knowledge and allows doctors to implement models directly in their electronic medical record systems (EMR) [29,83].
Another direct usage of AI in dermatopathology is tumor classification support, in which, using morphological characteristics, AI can distinguish between many tumor types like basal cell carcinoma (BCC) and cutaneous squamous cell carcinoma (cSCC) [84].
A study performed on 386 cases of basal cell carcinoma (BCC), cutaneous squamous cell carcinoma (cSCC), nevi, melanoma and other non-tumoral tissue with a result on WSI of 129,364 patches using the EfficientNetV2-S model revealed an accuracy of 98.7% for tumoral cases, with a confusion between melanoma and BCC-cSCC [31].
A study that created an end-to-end deep learning framework for skin tumors (neurofibroma, Bowen Disease and seborrheic keratosis) used two different approaches: a patch-wise classification by dividing each WSI image into patches and classifying them using different CNNs—the most high-performing being EfficientNetB6—and a classification by slide-wise aggregation, by combining the characteristics of the patches with an Attention Graph Gated Network (AGGN). The multitude of CNNs used (Xception, ResNet50, InceptionV3, Dual Path Network, EfficientNetB6), the optimization and the heatmaps used for interpretation improved the consistency of the developed model in relation to the pathologist [26].
The algorithms used for counting the mitoses were developed initially for breast carcinoma but applied also to melanocytic cutaneous lesions. A study performed on 99 cases using a CNN-based mitosis algorithm with a manual selection of ROIs detected 2868 candidate objects. After selection, there were 825 candidate mitoses identified in 61 cases (lesional or non-lesional), but with a high rate of false positive results (melanin pigment, other nuclei or artefacts). One advantage is that the algorithm can identify mitoses which are hard to observe, especially in atypical melanocytic lesions. There is still a need for fine-tuning for the algorithm to be able to make a distinction between melanocytic and non-melanocytic mitoses [50].
Another application is the screening and diagnostics of nevoid melanoma. The first use of Fast Random Forest for dermatopathology pre-screening was on two classification clusters of pixels on WSI (C1—normal clusters and C2—possible anormal clusters—nevoid melanoma) [47]. Cutaneous lymphomas could use advanced AI for detection and triage, subclassification depending on rare entities, identification or quantification of biomarkers and the prediction of prognostics and treatment response. There is a possibility of using other validated AI algorithms (melanoma, basal cell carcinoma) on cutaneous lymphoma for further validation [45].
The differential diagnosis of Melanoma Nodal Metastasis (NM) and Intra-Nodal Nevus (INN) was assessed using an AI algorithm on 196 sentinel node biopsies with a total of 485 WSI. There were 5956 annotated pixel-wise regions guided by immunohistochemistry. A CNN model was proposed with a U-NET architecture and two layers (parent-child). The architecture was designed on two layers: layer one (parent)—detection of quality tissue with the elimination of artefacts and layer two (child)—the detection of NM and INN in the zones validated by layer one. NM had a sensibility of 89% and a specificity of 94%, while INN had a sensibility of 78% and a specificity of 63%. The AI model also detected small tumoral foci, missed by the pathologist. The main advantage was the double detection (NM+INN) with a reduced rate of immunohistochemistry dependence, by training the algorithm with the morphological characteristics on H&E slides [33].
The UNet CNN model was used also to detect the clear excision margins in BCC by the use of both the classic UNet model and the UNet with ResNet34 encoder, also using deep supervision on 650 WSI of BCC and 3443 tissue sections with an accuracy of detection of 96.4%, a sensibility of 96.3% and a specificity of 36.5% [43].
A factor of hesitation for the implementation of AI in pathology is still represented by the black-box risks, e.g., the lack of transparency or the possibility of visualizing the decisional thinking of the algorithm. By implementing explicable AI technology (XAI) this hesitation might be reduced. Legal responsibility in cases of errors generated by AI is still a concern, and XAI may mitigate this concern by providing transparency in decision-making [20,85].
Even though AI evolves and new models are developing in real time, adaptive AI, in which AI models that adapt in real-time with new cases, raises questions in terms of the reproducibility of cases but also of responsibility in case of errors. Like in every field, in pathology, errors in the oncologic diagnostic may lead to cataclysmic consequences, therefore there is a need for adequate technical regulations [26,29,86].
Adaptative learning AI and the risk of “black-box” AI, regarding the lack of transparency in the decisional process of the AI algorithm may lead to a lack of low trustworthiness and difficulties in legal traceability, but may also lead to reproducibility concerns [20,85]. Table 1 integrates the main roles of AI in dermatopathology at the time of the study.

4. Research Direction 2—Integration of Digital Pathology and Standardization in Dermatopathology Practice

DP is no longer considered experimental or merely innovative and nowadays has reached a high degree of maturity and is implemented in hospitals, clinical centers, various pathology services and many academic institutions [19]. Digital infrastructure combined with whole slide imaging (WSI) has led to the transition from optical microscopy to complete digital analysis, even for the primary diagnosis. DP has a great utility in dermatopathology, where the complexity of the lesions and the histopathological variability may need a second opinion [84]. Besides this, combining WSI with molecular pathology and clinical data, DP and AI may lead to the early detection of aggressive tumors like melanoma, thereby increasing the quality of therapeutic decisions and the overall survival of the patients [77].
Because we live in the era of digitalization, many pathology services have totally transformed their workflow into a completely digital one. The implementation of WSI scanners on a large-scale basis, with cloud infrastructure and standardized international software for interpretation are the essential conditions to establish a well-organized telepathology service. The rapid evolution of high-speed internet access and the development of cloud systems is facilitating international collaboration. Digital infrastructure with high levels of cybersecurity is reinforcing the feasibility of telepathology [87,88].
The integration of DP into dermatopathology also has two important results: increasing the quality of medical education and supporting research and innovation. The teaching processes in histology, pathology and cellular biology have been reinterpreted by the integration of DP. Cases can be annotated, archived and very easily shared and the evaluation can be easily standardized. In dermatopathology, digital collections of cutaneous lesions may lead to superior visual training [48,83]. Research in dermatopathology may also be increased by using digital libraries of WSI which are structured and standardized, therefore helping computational pathology [48]. These represent the foundations for developing AI algorithms, retrospective studies, metanalyses and international collaborations in oncology and pathology.
DP and AI in dermatopathology have made significant progress in the last years, but as always, high development comes with significant limitations. The lack of interoperability between different DP and AI systems is one of the major limitations which may affect the standardization of the diagnostic process. Regarding cost, the implementation of DP and AI in pathology and dermatopathology incurs high initial costs, which is a major impediment for many medical centers [2,3,48,84,89]. Validation may raise concerns in each laboratory, even if the software or device is FDA- or IVD-approved, in terms of local validation, which may lead to delays in implementation [67,89,90,91,92].
Studies across pathologists shows that there exists professional support to implement DP in laboratories, especially for standardizable duties like the identification of mitoses, tumoral excision margins or immunohistochemical evaluation. Also, the standardization of WSI infrastructures and workflows is needed for global interoperability [49].
Table 2 integrates the main roles of digital pathology in dermatopathology at the time of the study.

5. Research Direction 3—Validation, Regulation, and Global Access Expansion Through Telepathology

Validation depends on various factors and should be classified as technical validation, in which, starting from the structure of the software, the developing code, the composition of the algorithm, user interface, and total performance all are technical components, and clinical validation, which always comes after technical validation, in which the developed software must comply to the impact of direct usage for diagnostics, especially in dermatopathology, where there might often be a difference between cancer or no cancer. This means that clinical validation relies mostly on the medical decision that is performed by the AI software [45,46].
As more laboratories are in a process of transition between classic pathology and digital pathology, this opens the possibility for real-life testing in many laboratories, ensuring multi-step testing in many different pathology services, with different workflows and different environments. Even though software receives the certification of an IVD software, validation goes further than the company that releases the software. Therefore, local validation (or third validation in the process) should be taken into consideration, before applying the AI software or telepathology software in the standard workflow of the pathology service. Validation should always be taken into consideration when testing AI software in terms of pathology, as each laboratory may use different devices, different scanners for WSI and different computers. Heterogeneity in testing is always necessary for approval by the FDA or the EC, and for the internationalization of the process [67,89,92,93,94].
AI software which is used in diagnostic procedures must be validated as medical device software and must be distinguished from research-use-only (RUO) software. For this, worldwide acceptance of AI software must be authorized by the authorities (the FDA in the USA or the European Commission (EC) in Europe) as medical software, with complete compliance with MDR and IVD recognition. Besides those accreditations, ISO protocols for medical devices which come with supplementary indications should be taken into consideration [89,92].
As of 2025, the FDA has approved almost 1000 AI-based medical devices, but the regulation of AI must be flexible and adapted to the rapid rhythm of development, coordinated through governmental agencies. Developers must maintain a high transparency of the AI algorithms and the results of developing an AI medical tool must be determined by the patient’s health, not only the operational or economic benefits [95]. A study performed on IVD validation showed that out of the 26 AI products identified for DP on the EEA/GB market, 24 were IVD-approved by auto-evaluation. Only 38% of the products had internal validation studies and 42% had external studies. An online registry for AI products of DP was developed (Register of AI products for digital pathology—https://osf.io/gb84r/ (accessed on 14 August 2025)) [89]
AI models designed for pathology, besides validation, need to be carefully documented. Every stage in production, development and validation should be precisely documented and this documentation should be supported by accredited institutions. In addition, for the software to be used in clinical practice, the algorithm needs to be completely explicable (interpretable AI). To serve as interoperable software, standardization needs to be implemented in terms of images and clinical data transfer and analyzing, such as DICOM for images and mostly HL7 for clinical data. This is a necessity and an obligation to be able to receive the accreditation for clinical usage. The risk assessment is strictly regulated by IVD and FDA regulations, and for this each software should be classified or evaluated through the risk-based classification of the IVD and FDA regulations [67,89,93,94,95,103,104,105].
In the absence of a structured ethical framework, AI may amplify the existing inequalities in dermatopathology. Without adequate control, AI might become an instrument that highlights the disparities between more developed medical centers and those which are not so developed. AI models can also acquire information from images provided through the optic tube of the microscope, representing a way of implementing DP and AI in services with limited resources [96,97,98]. The fact that there is not an ethical framework regarding AI in dermatopathology, the risk of exacerbating existing healthcare disparities in healthcare centers may become very significant, combined with the legal responsibility in case of a medical error. All of these limitations appear when the world evolves and technology gets better [29,48,79,106].
Cybersecurity nowadays is a concern and the implementation of very strict and serious regulations regarding medical data in every healthcare facility is necessary, especially in terms of telepathology and cloud-based systems, with GDPR/HIPAA regulations to be respected [19,77,78,84,90]. By focusing on continuous improvement, DP in dermatopathology will be improved in the future.
The integration of DP has faced many technical troubles in terms of standardization and infrastructure. A big limitation is the absence of interoperability between various systems, the necessity of very accurate and modern servers, the initial high costs for implementation and the need for standardized protocols for cybersecurity and archiving. International standards for medical pictures, such as DICOM, are rapidly evolving and widely accepted for WSI [2,99,100].
In terms of de facto usage in a laboratory, each process that involves quality assurance and control should be reconsidered when the transition is made to AI pathology software and DP implementation, regarding the pre-analytical, analytical and post-analytical process. To assure quality control, all personnel of the laboratory should be carefully instructed on how to use the devices or the software, and the FDA and the MDR should request the documented instructions of the personnel who will work with or use the validated software [67,93,94,103,104,105].
The future of telepathology depends on the development of collaborative medicine where dermatopathologists, dermatologists, surgeons, oncologists and molecular pathologists from other services construct the framework for an integrated therapeutical decision-making model [87,88,107]. The relevance of clinical studies in dermatopathology and the statistical power of multicentric networks are increased by telepathology, in terms of the development of new AI algorithms, the validation of predictive and diagnostics biomarkers and the evaluation of diagnostic interobserver variances [101,102]. Personalized medicine for melanoma will benefit from a holistic approach, in which histopathological examination needs to be contextualized in a clinical and molecular pathway [87,88,101,102].
Telepathology can be considered the branch of DP that brings together the transmission, visualization and interpretation from distance of the histopathological images from microscopic slides through communication systems. This allows for the establishment of the histopathological diagnosis without the physical presence of a pathologist. Telepathology can be classified as static, dynamic and hybrid, depending on the amount of control that involves a physical presence [40,107].
The progress in DP and WSI nowadays allows for a diagnosis in dermatopathology, and a second opinion without the physical movement of the samples. By this, it can be said that it can be a global framework for dermatopathology worldwide. Telepathology is a great way of optimizing human resources within a pathological service. AI algorithms can pre-classify routine cases and focus on those which may need extensive attention or a second opinion. Worldwide, there are pathology services which do not have specialized dermatopathologists. Telepathology is a real help in increasing the healthcare services provided by that service, in terms of using it to provide urgent diagnoses and avoid delays in the treatment of a malignant skin lesion [87,88,101,102].
An important point in developing telepathology is represented by the necessity of following GDPR rules (in Europe) and HIPAA (in USA). Cybersecurity remains a problem in terms of medical data, and a threat. Without establishing serious real-time data protection protocols, access control and audits for veracity, trust in DP and telepathology may be affected [19,78,84,90,91].

6. Conclusions, Foundations and Challenges of Implementing DP and AI in Dermatopathology

DP has now reached a level of maturity in which we can say that it is no longer the future, it is the present. With the variety of domains in which DP can be implemented, such as pathology services, hospitals, research centers and academic institutions, we can say that the use of DP and AI in dermatopathology has evolved very rapidly. DP is valuable in terms of the early diagnosis of aggressive cutaneous tumors such as melanoma, by integrating histopathological data, clinical data and molecular data, and thereby being able to increase the quality of medical activities, increasing the quality of life for the patients. Even though the COVID-19 pandemic has been a challenge worldwide, it can be said that in terms of developing DP, especially in dermatopathology, the pandemic forced the technology to develop and telepathology to evolve. DP and AI are already being applied in dermatopathology and being used with a high grade of accuracy in terms of tumor classification and distinguishing malignant cases from benign ones. DP also supports continuous medical teaching and research, enhancing the quality of teaching using new and advanced technologies. Standardization brings together multicenter databases and approaches through DP. The ethics and confidentiality of medical data are strongly improved by generative AI and federated learning, increasing trust regarding implementing AI into daily routine clinical practices. The development of CNN algorithms comes with an increased percentage of accuracy in histopathological diagnostic sand with telepathology that brings in a worldwide perspective, the quality of histopathological diagnostics is increasing. Multistep validation is necessary and remains the biggest challenge for the implementation of AI and DP in daily routines.
