Abstract
BACKGROUND: Survival outcomes in acral lentiginous melanoma (ALM) are worse than for cutaneous melanoma. Diagnostic delays are believed to contribute to worse outcomes in ALM, including advanced-stage disease at initial presentation. Acral lentiginous melanoma, especially in its early stages, may be difficult to discern from benign pigmented acral lesions.
OBJECTIVE: The purpose of this article is to provide a comprehensive review of the diagnosis and management of acral pigmented lesions.
MATERIALS AND METHODS: A literature review was performed. The outcomes included were the clinical and dermoscopic features and the management frameworks and considerations for acquired and congenital melanocytic nevi, acral melanosis, nonmelanocytic pigmented lesions, and ALM.
RESULTS: Original research studies were primarily included. The use of dermoscopy, such as the 3-step algorithm and blotch (irregular), ridge pattern (parallel), asymmetry of structures, asymmetry of colors, furrow pattern (parallel), fibrillar pattern (BRAAFF) checklist, increases the diagnostic accuracy of acral pigmented lesions with high specificity and sensitivity. Short-term digital dermoscopic surveillance can be used to manage acral lesions, and histopathology should be collected when there is a concern for ALM.
CONCLUSION: The use of dermoscopy and an understanding of how to manage acral lesions may limit the number of biopsies performed on the acral skin, decrease the time to diagnosis, and facilitate early detection of ALM.
