Hemangioma of the zygomatic bone.

Bony hemangiomas of the zygomatic bone are rare. This report represents the tenth citing in the literature. The most common signs and symptoms include swelling and pain or tenderness. Diagnosis can be made by plain radiographic studies followed by CT scanning or MRI. The treatment of choice is surgical excision with a rim of normal bone around the tumor. Malignant degeneration has not been reported unless radiotherapy had been used.
