Abstract
|
|
|
|
Hobnail hemangioma is a benign vascular tumor that typically presents as a small, solitary lesion on the trunk or limbs of young or middle-aged persons. Characteristically,the tumor has a targetoid appearance where a violaceous papule is surrounded by an ecchymotic rim. Hobnail hemangioma is characterized by a biphasic growth pattern of the neoplastic vascular structures and prominent matchstick-like endothelial cells. Based on the positivity of the endothelial cells for monoclonal antibody D2-40, it has been proposed that this tumor displays lymphatic differentiation. Angiolipomas are benign subcutaneous tumors that consist of mature adipocytes and blood vessels. They are usually multiple and they typically occur in young adults with an obvious male predilection. We describe here a case of hobnail hemangioma that occurred together with angiolipoma in an 8-year-old girl, who had a violaceous papule encircled by a peripheral ecchymotic halo on the left heel.
