Overview

Angiokeratoma is benign cutaneous injury of capillaries, resulting in small lesions on the skin, typically having a red to blue color and characterized by hyperkeratosis.

Classification

Angiokeratoma may be classified as:

• Angiokeratoma of Mibelli (also known as "Mibelli's angiokeratoma," "Telangiectatic warts") consists of 1- to 5-mm red vascular papules, the surfaces of which become hyperkeratotic in the course of time. The disease is named after Italian dermatologist Vittorio Mibelli (1860-1910).

• Angiokeratoma of Fordyce (also known as "Angiokeratoma of the scrotum and vulva," though not to be confused with Fordyce's spots) is a skin condition characterized by red to blue papules on the scrotum or vulva.

• Solitary angiokeratoma is a small, bluish-black, warty papule that occurs predominantly on the lower extremities.

• Verrucous vascular malformation (also known as "Angiokeratoma circumscriptum naeviforme") is a malformation of dermal and subcutaneous capillaries and veins, a congenital vascular malformation, which, over time, a verrucous component appears.
