EXPANSIVE OSSEOUS DYSPLASIA: CASE REPORT AND LITERATURE REVIEW

Abstract

Literature review was carried out and found 30 cases. According to the data found, the most affected sex is female at 35 ± 16.4 years, with location in the maxilla. A 33-year-old woman was diagnosed as having florid osseous dysplasia through radiographic examinations. Five years later, she was referred, exhibiting an expansive lesion of the mandibular anterior region. The intraoral examination revealed an expansion in the vestibular and lingual cortical bones, and the teeth showed displacement without alterations of pulp vitality testing and pain. The panoramic radiograph showed an expansive mixed lesion. Teeth resorptions were not visualized. The computed tomography showed a dense mixed lesion closely associated with the roots of the mandibular incisors. Intraoral incisional biopsy was performed, which proved difficult to detach from adjacent bone, and the specimen microscopically revealed a benign fibro-osseous lesion. The clinicopathologic features favored the diagnosis of expansive osseous dysplasia. The patient was referred for surgical evaluation. Literature review was carried out and found 30 cases.
