Angiokeratoma is a benigncutaneous lesion of capillaries, resulting in small marks of red to blue color and characterized byhyperkeratosis.Angiokeratoma corporis diffusum refers toFabry's disease,[1] but this is usually considered a distinct condition.
Multiple angiokeratomas, especially on the trunk in young people, are typical forFabry disease, genetic disorder connected with systemic complications.
In some instances nodular angiokeratomas can produce necrotic tissue and valleys that can harbor fungal, bacterial and viral infections. Infections can include staphylococcus. If the lesion becomes painful, begins draining fluids or pus, or begins to smell, a doctor may recommend excision and grafting.
Angiokeratoma of Mibelli (also known as "Mibelli's angiokeratoma,"[4] "Telangiectatic warts"[5]) consists of 1- to 5-mm red vascular papules, the surfaces of which become hyperkeratotic in the course of time.[5]: 589 The disease is named after ItaliandermatologistVittorio Mibelli (1860-1910).[6]
Angiokeratoma ofFordyce (also known as "Angiokeratoma of the scrotum and vulva," though not to be confused withFordyce's spots)[5] is a skin condition characterized by red to blue papules on the scrotum or vulva.
Solitary angiokeratoma is a small, bluish-black, wartypapule that occurs predominantly on the lower extremities.[5]: 590
Verrucous vascular malformation (also known as "Angiokeratoma circumscriptum naeviforme") is a malformation ofdermal and subcutaneouscapillaries andveins, a congenitalvascular malformation, which, over time, a verrucous component appears.[5]: 584
