Cavernous hemangioma mimicking nevus sebaceous

Abstract

Cavernous hemangiomas are congenital vascular malformations that are now known as venous malformations. They can occur in any tissue but are especially common in the skin, where they usually are seen at birth or within the first several years of life. Nevus sebaceous is a benign tumor of the sebaceous gland presenting from birth to adolescence. A 34-year-old male patient presented with an asymptomatic raised lesion over the scalp that was present since birth and had been increasing in size over the past 3 years. Provisional diagnosis of nevus sebaceous was carried out due to the site, age of appearance and non-blanchability, but histopathology showed features suggestive of cavernous hemangioma. We report this case for its misleading form of presentation.
