Intraosseous mandibular hemangioma. A case report and review of the literature.
Intraosseous vascular lesions are rare conditions, comprising only 0.5% to 1% of all intraosseous tumors. They mainly occur in the second decade of life especially in women. The most common locations are the vertebral column and skull; nevertheless, the mandible is a quite rare location. According to the World Health Organization, hemangiomas are benign vasoformative neoplasms of endothelial origin. However, the origin of central hemangioma is debatable. Some authors believe that it is a true neoplasm, whereas others state it is a hamartomatous lesion. Clinically, the patient may be completely symptom-free or may present discomfort, pulsatile bleeding, bluish discoloration, mobile teeth, derangement of the arch form or accelerated dental exfoliation. Most frequently radiographic finding is a multilocular radiolucent image with honeycombs or soap bubble appearance. Differential diagnosis includes neoplasms such as ameloblastoma, cystic lesions such as residual cyst, keratocyst and fibro-osseous lesions such as fibrous dysplasia. There are some therapeutic alternatives, although wide surgical excision remains as the gold standard. We now present a case report of a 51-year-old woman diagnosed in a mandibular hemangioma. Clinical, radiological and histological features of this unusual tumor are described.
