Leiomyoma with intracytoplasmic inclusion bodies in the oral cavity Open
Leiomyomas are benign tumors that arise from the smooth musculature and can occur in any part of the body where these muscles are present. However, leiomyomas of the oral cavity are rare because of the scarcity of smooth muscles at this si…
