angiokeratoma

(ăn′jē-ō-kĕr′ə-tō′mə)
n.
An intradermal hemangioma covered by a wartlike thickening of the horny layer of the epidermis.

angiokeratoma

Any of a group of vascular ectasias of the papillary dermis, which may produce papillomatosis, acanthosis, and hyperkeratosis of the epidermis, which are more common in women (female:male ratio, 3:1) and on the leg. Of the 8 types, Mibelli described an angiokeratoma affecting the fingers and toes and Fabry reported angiokeratoma circumscriptum as a localised lesion on the leg or trunk. Angiokeratomas are clinically important because they clinically mimic melanoma.

[5,7] Histologically, lymphangiomas have been classified into three types: lymphangioma circumscriptum (Papular angiokeratoma), classical lymphangioma circumscriptum (Angiokeratoma circumscriptum) and cavernous lymphangioma (Hygroma or cavernous haemangioma).
Five varieties of angiokeratoma are generally recognized: i) generalized systemic type - angiokeratoma corporis diffusum (ACD); ii) bilateral form occurring on the dorsa of fingers and toes - angiokeratoma of Mibelli; iii) localized scrotal/vulval form - angiokeratoma of Fordyce; iv) solitary papular angiokeratoma; and v) multiple unilateral papular and plaque like, usually on lower limbs - angiokeratoma circumscriptum (naeviforme).8
* Angiokeratoma circumscriptum usually present as papules that commonly coalesce to form plaques.
FINAL HISTOLOGICAL DIAGNOSIS: Angiokeratoma circumscriptum.
Localized angiokeratoma may be solitary or multiple and has been further classified into Fordyce's angiokeratoma (distributed on the genitals), Mibelli's angiokeratoma (dorsum of toes and fingers) and angiokeratoma circumscriptum naeviforme (unilateral large keratotic plaques).
