Special Issue Information

Dear Colleagues,

Skin-related diseases, from common issues such as eczema or acne to more severe conditions such as skin cancer or psoriasis, pose significant challenges for both patients and healthcare providers. Recent advancements in understanding the pathogenesis of these diseases have resulted in groundbreaking insights into their underlying molecular mechanisms. These discoveries are paving the way for innovative therapeutic approaches and more effective treatment.

The pathogenesis of skin diseases involves complex interactions between genetic factors, immune responses, environmental influences, and microbial communities. Researchers are increasingly focusing on inflammation, immune system dysfunction, and alterations in skin barrier function as key contributors to disease development. The skin microbiome is also emerging as a critical player in maintaining skin health and modulating disease processes.

In response to these insights, new therapeutic strategies are being developed. Targeted biologics, small molecules, and gene therapies are revolutionizing treatment options, offering more personalized approaches for patients. Moreover, advances in topical treatments, gene-editing technologies, and microbiome-based therapies have the potential to transform skin disease management in the near future.

For the present Special Issue, we invite researchers in both basic science and clinical/translational research to submit their manuscripts related to the topics described above.

Acne vulgaris is a multifactorial inflammatory skin disorder that significantly impairs quality of life and may signal underlying systemic dysfunction, particularly in adult women with treatment-resistant or atypical presentations. This case series presents three clinically and etiologically distinct examples of persistent acne in female patients, each associated with different contributing factors: long-term topical corticosteroid misuse, polycystic ovary syndrome (PCOS), and metabolic syndrome with autoimmune thyroiditis. All cases underwent comprehensive dermatologic evaluation, endocrine/metabolic assessments, and personalized therapeutic interventions, ranging from corticosteroid withdrawal and barrier repair to hormonal modulation and insulin-sensitizing therapy. Clinical progression was monitored for up to six months, revealing favorable responses in all cases, with substantial lesion clearance and improved skin quality. These real-world cases highlight the importance of an integrative, interdisciplinary diagnostic approach in refractory acne and support the need for individualized, long-term management strategies tailored to underlying systemic contributors.

Dermatofibrosarcoma protuberans (DFSP) is a rare, soft-tissue sarcoma characterized by dermal, finger-like projections and high local recurrence rates. Complete surgical excision is the primary treatment goal and Mohs micrographic surgery (MMS) is the accepted approach for achieving disease-free margins. Despite the effectiveness of MMS, it has limitations when treating DFSP, with documented local recurrences. This paper presents our experience and treatment modality for DFSP, using MMS with an additional “safety margin”. This technique seeks to ensure free surgical margins and potentially lower recurrence rates. This is a retrospective analysis of patients treated for DFSP over a 10-year period. All patients underwent MMS, followed by an additional, circumferential excision of 2–5 mm. Twenty-two patients were treated surgically for DFSP from 2014 to 2023. The median age at presentation was 42.5 years. Four patients (18%) had positive disease margins on the additional safety marginal excision, two had negative MMS slides, and the other two were positive for DFSP. The mean follow-up time was 27 months, and no local recurrences were observed during that time. The surgical method presented here includes an additional excision of the surrounding margins following MMS for DFSP. This technique provides a tool to overcome the limitations of MMS in treating this tumor, aiming to reduce local recurrence. Full article

Non-melanoma skin cancer (NMSC), comprising basal cell carcinoma (BCC) and cutaneous squamous cell carcinoma (cSCC), represents the most common type of cancer worldwide, particularly among Caucasians. While BCC is locally invasive with minimal metastatic potential, cSCC is a highly aggressive tumor with a significant potential for metastasis, particularly in elderly populations. Tumor development and progression and the metastasis of cSCC are influenced by a complex interplay between tumor cells and the tumor microenvironment. Recent research highlights the importance of various immune cell subsets, including T cells, tumor-associated macrophages (TAMs), and dendritic cells, in influencing tumor progression, immune evasion, and treatment resistance. This review outlines key regulatory mechanisms in the immune tumor microenvironment (TME) of cSCC and explores the role of cytokines, immune checkpoints, and stromal interactions. We further discuss the relevance of three-dimensional (3D) in vitro models such as spheroids, organoids, and tumor-on-chip systems as tools to mimic immune–tumor interactions with higher physiological relevance, such as macrophage activation and polarization against cSCC cells. Globally, 3D models offer new opportunities for immunotherapy screening and mechanistic studies. Understanding the immune landscape in cSCC through advanced modeling techniques holds strong clinical potential for improving diagnostic and therapeutic strategies. Full article
