Oral leiomyoma: a case report.

Oral leiomyoma is a benign smooth muscle tumour, that occurs most frequently in the uterine myometrium, gastrointestinal tract, and skin. Ocurrence in the oral cavity is considered rare, probably because of the paucity of smooth muscle tissue at this level. Smooth muscle tumours can occur at any age an usually is appear as a slow growing, firm mucosal nodule.
