Abstract
|
|
|
|
Hobnail hemangioma is a benign vascular tumor that typically presents as a small, single lesion on the skin of the trunk or limb. It occurs mainly in young or middle-aged adults (mean age: 30 years) but rarely in childhood. Histologically, hobnail hemangioma is characterized by a biphasic growth pattern, with dilated vascular spaces lined by hobnail endothelial cells in the superficial dermis, and collagen dissection narrow vascular channels in the deeper dermal parts, as well as inflammatory aggregates, fibrosis, and hemosiderin deposits. We report a case of hobnail hemangioma in a 10-year-old girl who had a violaceous papule surrounded by an ecchymotic halo on the left thigh. She underwent treatment with surgical excision with primary closure. To the best of our knowledge, our case is the first reported case of childhood hobnail hemangioma in Korean dermatological literatures.
