We describe the case of a 45-year-old man who presented with a 5-month history of unilateral pruritic linear erythematous papules and atrophy on the chin and mandibular area. Dermoscopy showed areas of cicatricial alopecia with absence of follicular openings, perifollicular erythema and pigment. Lichen planopilaris of the face is a rare variant with only 13 cases reported in the literature.

Acral melanoma is the most frequent subtype in the Asian and Mexican mestizo populations. 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.
