Hemangioma of the zygoma

Although hemangioma is a common soft tissue tumor, in the oral and maxillofacial region, hemangioma of bone is very rare, especially in a zygoma. A 47-year-old woman was admitted complaining of a hard mass in the zygomatic region, which had first been noticed 1 year previously. Plain roentgenograms revealed a well-marked spoke-wheel trabeculation diverging from the center of the mass. CT scans demonstrated the same findings. From the excision biopsy, the lesion was suspected to be cavenous hemangioma with malignant hemangioendothelioma. We performed complete excision and reconstructed the full-thickness defect of the zygomatic bone with an artificial bone made ahead of operation and calcium phosphate cement. The implant, maintained at 7 months, continued to have a successful outcome. It is useful in zygomatic bone reconstruction because of shortening of operation time and control of bleeding, conditioning the figure side.
