Hereditary papulotranslucent acrokeratoderma: a case report and literature review.

Hereditary papulotranslucent acrokeratoderma is a rare autosomal-dominant syndrome of the hands and feet characterized by persistent, asymptomatic, yellowish to white papules and plaques associated with fine-textured scalp hair and an atopic diathesis. Histopathologically, focal hyperkeratosis, hypergranulosis, and acanthosis of the epidermis are seen. We present a case of hereditary papulotranslucent acrokeratoderma in a young adult woman. The literature of this unusual condition is reviewed, and its relationship to acquired papulotranslucent acrokeratoderma is discussed.
