Abstract
- Targetoid hemosiderotic hemangioma (THH) is a solitary vascular tumor typically occurring in young or middle-aged persons, and affecting the limbs or trunk. Characteristically, the lesion has a "targetoid" appearance where a violaceous papule is surrounded by an ecchymotic or brown ring that can expand or subsequently disappear with the persistence of the central papule. 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. We report a 17-year-old girl who presented showing typical clinical and histological features of targetoid hemosiderotic hemangioma.
