Abstract
- Focal acral hyperkeratosis is a rare skin disorder, initially described by Dowd et al., which is sporadic or inherited in an autosomal dominant way. Clinically, the condition presents with small yellowish to white papules located on lateral aspects of the hands and feet. Histopathological alterations are limited to the epidermis and there are no changes in the elastic fibers of the dermis. In this case report, a 14-year-old girl had a two-year history of persistent, asymptomatic, multiple papules along the border of the hands and feet. A histologic section of papules from the left hand and foot showed marked hyperkeratosis and hypergranulosis of epidermis.
