Angioleiomyoma of the cheek: a case report

Abstract

Angioleiomyoma is a form of subcutaneous vascular leiomyoma that usually occurs in the extremities. Leiomyoma of the oral cavity represents only 0.4% of soft tissue neoplasms and 0.06% of leiomyomas. Isolated cases of angioleiomyoma have been reported in the knee and lower thigh, gastrointestinal tract, genital and renal tract, and brain. Histopathologic examination by biopsy is necessary to establish a diagnosis, and immunohistochemical staining, along with conventional hematoxylin-eosin staining, is important. The differential diagnosis includes hemangioma and angiosarcoma. At present, surgical resection is the standard therapy for leiomyoma, and recurrence is extremely rare. We report a rare case of angioleiomyoma of the cheek in a 45-year-old man. The postoperative course was uneventful, without complications.
