Angioleiomyoma is a benign tumor of smooth muscle originating in blood vessels. It is usually located in the lower extremities of middle-aged women and rarely occurs in the oral cavity. We report a case of angioleiomyoma developing at the mouth angle.
A 71-year-old man noticed a painless tumor at the right angle of the mouth. The tumor was thumb-head size, with a sharp border and elastic hardness. The clinical diagnosis was a benign tumor of the mouth angle. The tumor was surgically resected with the patient under local anesthesia. The resected tumor was solid, white-yellow, and measured 15×10×10mm.
Histopathologic examination showed angioleiomyoma, solid type.
