Mythology to reality: case report on a giant cutaneous horn of the scalp in an African American female.

We present a case study of a patient with a rare and disfiguring dermatologic condition known as cornu cutaneum, or giant cutaneous horn (GCH). While this condition has been well described in people of European and Asian ancestry, its presence in African populations is perceived to be rare and has not been reported in the literature until recently. We present the case of cornu cutaneum in a woman of African descent, contributing to the recent evidence that this condition may not be as rare in African populations as believed. Etiologic factors, epidemiology and management are also reviewed.
