Dermoscopic Findings Of Scalp Aplasia Cutis Congenita

Aplasia cutis congenita (ACC) is a rare disease characterized by congenital absence of skin, affecting preferentially the scalp. Diagnosis is made clinically; however, recent studies have shown that dermoscopy can be a useful tool for the diagnosis and differentiation from sebaceous nevus. The clinical findings include a shiny atrophic alopecic patch associated with dermoscopic findings of absent follicular openings, thicker vessels and a distinct collar hypertrichosis. We report 2 cases of alopecia presenting from birth. At dermoscopy, the absence of follicular openings and the increase in the caliber of vessels led us to establish the diagnosis of ACC. (C) 2016 S.
