Atypical dermoscopic presentation of an acral congenital melanocytic nevus in an adult: parallel ridge pattern and its histologic correlation
Keywords:
congenital, acral, nevi, dermoscopy, histopathologyAbstract
Acral melanoma is the most frequent subtype in Asian and Mexican mestizo population. Dermoscopy is a noninvasive diagnostic technique that helps the differential diagnosis of pigmented skin lesions on acral volar skin.
We herein present a case of acral congenital melanocytic nevus with a parallel ridge dermoscopic pattern. Since the parallel ridge pattern in a melanocytic lesion of the acral skin is classically ascribed to melanoma, the present case can be definitely labeled as ‘atypical’ and worth of being elucidated in its histopathological correlates.
