Cemento-ossifying Fibroma: A Case Report.

Cemento-ossifying fi broma is a benign rare tumor of mesenchymal origin seen in the third or fourth decade in females. It arises from the mesenchymal blast cells of the periodontal ligament and can mature into cementum, bone, or fi brous tissue or varying proportions of each. Th e lesion is most commonly seen in the jaw. It appears as a well-defi ned circumscribed unilocular radiolucent lesion. Radio-opacity of the lesion depends on the concentration of cement or bone or in the concentration of both. We present the imaging features of cemento-ossifying fi broma in a 73-year-old female patient, involving the left maxilla.
