A Case of Leiomyoma of the Auricle

ABSTRACT

Leiomyoma is benign neoplasm of smooth muscle origin, which generally originate in gastrointestinal and female genital tract. Within head and neck, the common sites are the cervical esophagus and/or oral cavity. Their occurrence in the ear is extremely rare. There have been reported less than ten cases of leiomyomas of auricle in the world and can not be found in the Korean literature. Leiomyoma arising from auricle is classifed into two types, one from the erector pilar muscle and the other from the muscular coats of blood vessel. We present a case of leiomyoma in scapha of the ear. This benign tumor was treated by complete excision. This tumor was small, round, firm, solitary and microscopically well-encapsulated. The clinical and pathologic findings of auricular leiomyoma were described.
