Unusual presentation of an ossifying fibroma in a young adult in mandibular region

A benign bone neoplasm known as an osseous fibroma is frequently referred as fibro-osseous lesion. It has a stronger preference for females and is thought to have originated from periodontal membrane. Maxilla is less often afflicted than the mandible. This bone neoplasm is made up of highly cellular, fibrous tissue with varied levels of calcified tissue, which may resemble cementum, bone, or both. Depending on the degree of calcification, the lesions are either entirely radiolucent, mixed, or fully radiopaque with a radiolucent margin. Due to its propensity for recurrence and potential for malignant change, ossifying fibromas necessitate extensive surgery. In this case, a 20-year-old female had a large ossifying fibroma of mandible.
