Central hemangioma of the maxilla: Report of a case with an exophytic growth

Abstract

A case of intraosseous hemangioma occuring in the maxilla of a 74 year-old-female is described. A radiolucent lesion in the maxilla pointed out by her dentist grew rapidly in a month. CT examination revealed an intraosseous mass lesion with scalloping margins and rapid enhancement with contrastive media. MRI indicated a well-demarcated and exophytic lesion with high T2-weight signals. The lesion, measuring 20 x 38 x 58 mm in size, was clinically suspected of malignancy and surgically resected together with the right half of the maxillary bone. Histopathologically, the lesion was a fibrous granulation tissue absorbing the maxillary bone and expanding into the oral mucosa. It was largely occupied with blood coagulae in the center and contained many dilated blood vessels with single-layered endothelial linings in the periphery including the bone. This is the first case report of central hemangioma with an exophytic growth. © 2004 Elsevier Ltd. All rights reserved.
