    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.

    Rare case of recurrent angiokeratoma of Fordyce on penile shaft.
    Urology 2006 Oct;68(4):891.e1-3

    Angiokeratomas are benign cutaneous vascular lesions characterized by dilated thin-walled blood vessels lying in the upper part of the dermis, mostly associated with an epidermal reaction such as acanthosis and/or hyperkeratosis. Angiokeratomas of Fordyce are predominantly located on the scrotum and are only rarely found on the penis and then usually on the glans penis. We report a rare case of angiokeratoma of Fordyce located on the shaft of the penis and associated with two recurrences after appropriate surgical excision. Read More

    Background: Angiokeratoma is a wart-like vascular lesion of the skin. There are five types of angiokeratoma: the Mibelli-type, the Fordyce-type, the solitary and multiple (papular) types, the angiokeratoma circumscriptum, and the angiokeratoma corporis diffusum. The "Mibelli-type" occurs on the acral sites, mainly digits, of young people affected by repeated attacks of chilblain, which result in a deleterious effects on vessel walls. Read More

    Department of Dermatology, University Hospital, Basel, Switzerland.
    Angiokeratomas are vascular lesions which are defined histologically as one or more dilated blood vessel(s) lying directly subepidermal and showing an epidermal proliferative reaction. At the center of pathogenesis there is a capillary ectasia in the papillary dermis. The epidermal changes in all forms of angiokeratoma are secondary. Read More

    The term 'angiokeratoma' includes a wide range of dermatological conditions of hyperkeratotic vascular disorders with a similar histologic combination of hyperkeratosis and superficial dermal vascular ectasia. Angiokeratomas can be classified into localized and systemic forms. Angiokeratoma of Fordyce (AKF) is a localized form of angiokeratoma, clinically characterized by 1- to 6-mm, black, blue, or dark red, dome-shaped papules located on the scrotum, shaft of penis, labia majora, clitoris, inner thigh, and lower abdomen.
