Fıbrous Dysplasıa of the Posterıor Mandıble Wıth One Year Follow Up, A Rare Case Report

Background/Aıms: Fibrous dysplasia is a non-neoplastic, developmental hamartomatous bone disorder that typically manifests during active skeletal growth and often stabilizes over time. This report aims to present the clinical, radiological, and histopathological findings of a patient diagnosed with fibrous dysplasia in the posterior mandible. Materıals And Methods: A 22-year-old female patient with long-standing swelling and facial asymmetry in the posterior mandible was examined. Radiographic imaging and histopathological analysis of an incisional biopsy were performed to confirm the diagnosis. Results: Clinical examination revealed swelling and facial deformity without pain or functional impairment. Radiographs showed a poorly defined radiopaque lesion with buccal and lingual cortical expansion and a ground-glass appearance. Histopathology confirmed fibrous dysplasia. A conservative management approach involving periodic monitoring was adopted. Conclusıon: Fibrous dysplasia in the mandible can present with facial asymmetry without pain. Conservative follow-up is a viable management option in stable cases. Long-term monitoring is essential to detect any changes in lesion size or malignant transformation.
