[Leiomyoma of tongue: a case report].

Oral leiomyoma is a benign smooth muscle tumor. Leiomyoma occurs most frequently in the uterine myometrium, gastrointestinal tract, and skin. Occurrence in the oral cavity is considered rare, probably because of the paucity of smooth muscle tissue at this area. Smooth muscle tumors can occur at any age and usually appear as a slow growing, firm submucosal nodule. Most lesions are asymptomatic, although occasional tumors can be painful. The most common sites are lips, palate and tongue. The diagnosis of leiomyoma in the oral cavity is mainly determined by histological studies. The purpose of this article is to present a case of a 48 year-old woman with a leiomyoma of tongue.
