Angioleiomyoma of the external auditory canal
American Journal of Otolaryngology, 2007Angioleiomyoma is a rare form of leiomyoma that accounts for about 5% of all benign tumors of soft tissues and arises from the smooth muscle cells of the tunica media of vascular structures. The peak of incidence is between the third and sixth decade of life, with a female preponderance. Morimoto [1] has classified these tumors into 3 histologic types:
