Cavernous hemangioma of the external ear canal.

Cavernous hemangiomas are benign tumors of blood vessel origin. Cavernous hemangiomas arising from the tympanic membrane with or without involvement of the skin of the deep external auditory canal may occur in rare cases. In this paper, the clinical and pathological findings in the first recorded case of a patient with a cavernous hemangioma arising from the skin of the deep external canal with no involvement of the tympanic membrane are presented.
