Demystifying the Mystified - An Ambiguous Presentation of Cemento-ossifying Fibroma in Maxilla.

Cemento-ossifying fibroma is a slow growing benign tumor of mesenchymal origin. It is typically found in craniofacial bones, frequently involving the mandible and it tends to occur in third and fourth decade of life with predilection for women. Occurrence of this lesion in maxilla is a rare entity. We report one such case of cemento-ossifying fibroma of size 5x4 cm on upper left maxilla in 38 year old female patient which is an unusual presentation.
