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.


Angiokeratoma may be classified as:

  • Angiokeratoma of Mibelli (also known as "Mibelli's angiokeratoma,"[1] "Telangiectatic warts"[2]) consists of 1- to 5-mm red vascular papules, the surfaces of which become hyperkeratotic in the course of time.[2]:589 The disease is named after Italian dermatologist Vittorio Mibelli (1860-1910).[3]
  • Angiokeratoma of Fordyce (also known as "Angiokeratoma of the scrotum and vulva," though not to be confused with Fordyce's spots)[2] 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.[2]:590
  • 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.[2]:584
