An Bras Dermatol. 2015 May-Jun;90(3 Suppl 1):150-2. doi: 10.1590/abd1806-4841.20153876.

Abstract

The term 'angiokeratoma' includes a wide range of dermatological conditions of hyperkeratotic vascular disorders with a similar histologic combination of hyperkeratosis and superficial dermal vascular ectasia. Angiokeratomas can be classified into localized and systemic forms. Angiokeratoma of Fordyce (AKF) is a localized form of angiokeratoma, clinically characterized by 1- to 6-mm, black, blue, or dark red, dome-shaped papules located on the scrotum, shaft of penis, labia majora, clitoris, inner thigh, and lower abdomen. We describe herein a case of giant angiokeratoma of Fordyce on shaft of the penis in an elderly man, clinically masquerading as keratoacanthoma.
