Abstract

|
Targetoid hemosiderotic hemangioma (THH) is a solitary vascular tumor affecting the limbs or trunk, typically occurring in young or middle-aged persons. The lesion has a "targetoid" appearance, where a violaceous papule is surrounded by an ecchymotic or brown ring. THH is characterized histologically by dilated vascular structures in the superficial dermis lined by prominent hobnail endothelial cells and collagen-dissecting, rather narrow neoplastic vessels in the deeper parts of the lesion. It is important to distinguish this tumor from patch stage of Kaposi’s sarcoma, solitary angiokeratoma, and retiform hemangioendothelioma. We report a 12-year-old girl showing typical clinical and histological features of targetoid hemosiderotic hemangioma.
