Abstract
Malignant smooth-muscle tumors are common in the uterus and gastrointestinal tracts, but the occurrence of these neoplasms in the oral cavity is rare.
Oral leiomyosarcomas have been reported on only 30 occasions in the world literature. An additional case of leiomyosarcoma of the maxilla in a 42-year-old female is reported. The relevant features of leiomyosarcomas were reviewed and discussed.
