Cemento-ossifying fibroma of mandible.

Cemento-ossifying fibromas are relatively rare benign, non-odontogenic tumours of the jaw, a subdivision of fibro-osseous lesions. These tumours occur in the third and fourth decades of life, with predilection for women. Majority of the lesions are found in the posterior region of the mandible. We present a rare case of cemento-ossifying fibroma involving the mentum of the mandible in a 50-year-old lady and discuss the plain radiographic and computed tomographic features of the condition.
