Vascular Leiomyoma of oral cavity: A case report in young male patient.

Abstract

Vascular Leiomyoma of the oral cavity is an uncommon benign soft tissue neoplasia arising from the tunica media of the smooth muscle cells. We reported a rare case of Vascular Leiomyoma involving the retromolar trigone area of a young man. A 24-year-old male presented with a slowly growing mass in the retromolar area, which was associated with pain and difficulty in opening of mouth and eating and drinking. A punch biopsy was taken and sent for histopathological examination which revealed a benign angiomatous lesion. The mass was excised, and the adjoining area was curetted. Histopathological examination confirmed the diagnosis of Vascular Leiomyoma. The immunohistochemistry of cells shows: alpha-smooth muscle (+); vimentin (+), Desmin, actin (+), and S100 (-). Angioleiomyomas are benign lesions, but malignant transformation is a possibility so careful histologic inspection is necessary to distinguish these lesions from their malignant counterpart.
