A Case of Hobnail Hemangioma

ABSTRACT

Hobnail hemangioma(HH) is a benign acquired vascular tumor of endothelial origin which should be differentiated from other malignant vascular neoplasm such as Kaposi's sarcoma or angiosarcoma. We report a case of hobnail hemangioma in a 21-year-old woman who had a dusky-red patch on her left shin. Histologically, ectatic vascular channels with a single layer of plumped endothelial cells were seen and the vascular channels seemed to dissect the collagen bundles. She underwent treatment with surgical excision with primary closure.
