title: Cavernous hemangioma--uncommon presentation in zygomatic bone.
abstract: Hemangiomas are benign vascular neoplasms characterized by an abnormal proliferation of blood vessels. They may occur in any vascularized tissue including skin, subcutaneous tissue, muscle, and bone. Intraosseous hemangiomas are uncommon, constituting less than 1% of all osseous tumors. The most frequent sites are the calvaria and the vertebral column. Involvement of the facial bones is rare and occurs most commonly in the maxilla, mandible, and nasal bones. In literature, only 20 cases of zygomatic involvement have been reported. We report a case of an intraosseous hemangioma of the zygoma with the history and physical findings of slowly growing, bony, hard tumor causing facial and ocular deformity. The typical clinicopathologic and radiologic findings helped to set up the correct diagnosis. Early recognition and excision are recommended to preserve facial contour. Operative blood loss is minimal, and there is no need for preoperative angiography.
