The Advantages of Dermoscopy in the Diagnosis of Acral Melanoma from Other Podiatric Lesions. A Literature Review
- Melanoma is one of the most common primary malignant tumors arising in the lower extremity. [1]
- It is crucial to diagnose melanoma as quickly and as efficiently as possiblefor a better prognosis.[2]
- The use of dermoscopy is helpful in diagnosing such conditions. Dermoscopy is a non-invasive, in-vivo technique primarily used in the examination of pigmented skin lesions. This procedure allows the visualization of subsurface skin structures in the epidermis, dermoepidermal junction, and upper dermis – structures not visible to the naked eye.




Objectives
- This poster reviews the literature and describes the advantages of dermoscopy in the field of podiatry by assessing all the dermoscopic criteria that ensure a positive predictive value of diagnosing an acral melanoma from an acral nevus.
- Additionally, it analyzes cases of misdiagnosis of a plantar-pigmented wart and a diabetic ulcer from a melanoma.

Discussion
- The use of dermoscopy is slowly evolving in podiatry. Dermoscopy is a less invasive yet efficient method that can minimize the patient’s exposure to anesthesia and prevent the formation of a biopsy induced ulcer in diabetic patients.
- While controversy remains over sensitivity and specificity of using a dermatoscope alone to diagnose pedal lesions, particular attention should be paid to the accuracy of diagnosing a lesion when dermoscopy is used in conjunction with a biopsy.
- From the literature we can conclude that dermoscopy can improve the clinician’s ability to make the correct diagnosis of an unknown podiatric lesion.
- With further research of dermoscopic patterns and improved physician training, dermoscopy has the potential to become the primary diagnostic tool for the evaluation of dermatological lesions.
