We have given the name "hereditary papulotranslucent acrokeratoderma" (HPA) to a new syndrome consisting of persistent, asymptomatic, yellowish-white, translucent papules and plaques that appear on the hands and feet, associated with fine-textured scalp hair and atopic diathesis. Histologic study of the translucent lesions showed orthohypergranulosis, acanthosis, and a relatively normal dermis.
