An angiomyoma is a benign tumor of the smooth muscle that originates in the blood vessels and is usually located in the extremities. Here, we report out experience with an extremely rare case of an angiomyoma that arose from the lower lip in a 29-year-old man. He had first noticed symptoms a few years ago. He was referred to our department with a complaint of incongruity with the tumor. It was a 1-cm, painless, non-tender mass on the labial mucosa of the left lower lip. Thus, enucleation of the tumor was performed. Microscopically, the tumor consisted of masses of leiomyoma and endothelial cells. The histopathological diagnosis was angiomyoma. Postoperative observation has revealed no recurrence, as of 3.9 years after surgery.
