Angiokeratoma is a benign cutaneous lesion of capillaries, resulting in small marks of red to blue color and characterized by hyperkeratosis.

Angiokeratoma corporis diffusum refers to Fabry's disease,[1] but this is usually considered a distinct condition.

[3] Multiple angiokeratomas, especially on the trunk in young people, are typical for Fabry 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.

Angiokeratomas characteristically have large dilated blood vessels in the superficial dermis and hyperkeratosis (overlying the dilated vessels).
