Angioleiomyoma in the retromolar trigone region

ABSTRACT

Leiomyoma is a benign soft tumor of smooth muscle origin which is rarely found in the oral cavity. The diagnosis of leiomyoma isfundamentally based on its histopathologic characteristics requiring specific staining methods and careful microscopic analysisdue to the high possibility of misdiagnosis. The present paper describes a case report of recurrent oral vascular leiomyomain the retromolar trigone region and performs a brief literature review. Specific staining methods were performed such asMasson’s trichrome and immunohistochemistry for smooth muscle actin. Prognosis of oral leiomyoma is excellent.
