Synopsis

Microvenular hemangioma, also known as microcapillary angioma or microcapillary hemangioma, is a rare, benign, acquired vascular proliferation. It typically presents as a solitary, asymptomatic, purple to red papule, plaque, or nodule on an extremity or the trunk. Young adults are most commonly affected, and there is a slight female predominance. Occasionally, there may be pruritus, tenderness, or multiple lesions.

The etiology of this vascular growth is unclear. No clear predisposing medical history or risk factors have been identified. There have been case reports of young women who developed microvenular hemangiomas who recently changed hormonal contraceptives or were pregnant. In addition, multiple microvenular hemangiomas have been reported in a patient with POEMS syndrome (polyneuropathy, organomegaly, endocrinopathy, monoclonal gammopathy, and skin changes).

Most microvenular hemangiomas grow slowly and stabilize in size, typically less than 2 cm in diameter. They do not recur after excision.
