We report a case of myopericytoma arising in the buccal region. A 73-year-old woman was referred to our clinic because of a painless swelling in the left cheek. The first medical examination revealed a dark-purple, small hen's egg-size, elastic soft, movable nodule in the left side of the buccal region. Computed tomographic, magnetic resonance imaging, and angiographic image analysis indicated a clinical diagnosis of hemangioma. The tumor was surgically resected 48 hours after embolization of the left facial artery. Histopathologically, oval shaped, α-SMA positive cells were arranged circumferentially around stag horn-shaped blood vessels in a multilayered fashion. These findings indicated a pathological diagnosis of myopericytoma. There have been no signs of recurrence of the tumor for 7 years 1 month since the operation.
