Angiokeratomas are benign proliferations of dilated thin-walled blood vessels in the upper dermis with overlying epidermal hyperkeratosis. There are several clinical variants of angiokeratomas: 1. Fordyce: smooth reddish-purple papules on scrotum or vulva; 2. Mibelli: hyperkeratotic papules on fingers or toes, solitary, multiple, or circumscriptum (grouped papules usually on an extremity); 4. angiokeratoma corporis diffusum, widespread papules that are a manifestation of one of several inherited lysozomal storage diseases. Herein, we report a rare case of multiple angiokeratomas of Fordyce on the corona of the glans penis.
