Toothache induced by an angioleiomyoma of the nasolabial groove: a case report.

Angioleiomyoma, a benign soft tissue tumor composed of smooth muscle cells and vascular endothelium, occurs most commonly in the extremities, the lower leg being a common site of occurrence. It rarely is found in the head and neck area, especially in the nasolabial groove. Surgical excision is the gold standard for diagnosis and treatment of angioleiomyoma; a preoperative diagnosis may be difficult.
