Targetoid Hemosiderotic Hemangioma

Targetoid Hemosiderotic Hemangioma (pronunciation: tar-get-oid he-mo-si-der-otic he-man-gee-oma), also known as Hobnail Hemangioma, is a benign vascular lesion of the skin. The term 'Targetoid' is derived from the lesion's target-like appearance, with a central red or purple papule surrounded by an ecchymotic ring. 'Hemosiderotic' refers to the presence of hemosiderin, a form of iron-storage complex, within the lesion. 'Hemangioma' is a general term for a benign tumor of blood vessels.

Clinical Presentation

Targetoid Hemosiderotic Hemangioma typically presents as a solitary lesion, often on the limbs or trunk. The lesion is usually less than 1 cm in diameter and has a characteristic appearance of a central red or purple papule surrounded by an ecchymotic ring. The lesion may be asymptomatic or associated with mild tenderness.

Histopathology

Histologically, Targetoid Hemosiderotic Hemangioma is characterized by a proliferation of small blood vessels with hobnail endothelial cells. There is often a peripheral rim of hemosiderin-laden macrophages, giving the lesion its characteristic targetoid appearance.

Differential Diagnosis

The differential diagnosis for Targetoid Hemosiderotic Hemangioma includes Kaposi's Sarcoma, Pyogenic Granuloma, and Angiokeratoma. Clinical and histological features are usually sufficient to distinguish Targetoid Hemosiderotic Hemangioma from these other entities.

Treatment

Treatment is usually not necessary for Targetoid Hemosiderotic Hemangioma as the lesion is benign and often self-resolving. However, if the lesion is symptomatic or cosmetically unacceptable, treatment options include surgical excision, laser therapy, or cryotherapy.
