Cemento-ossifying fibroma (COF) has been recently classified under fibro-osseous lesions of the jaw. It is a relatively rare and benign jaw tumour that has a plethora of histologic appearances, where the cells can differentiate into cementum, lamellar bone, fibrous elements or an admixture of all. The terminology, diagnostic criteria and consensus as to the origin of the tumour is confusing and often controversial; other terms commonly used are ossifying fibroma (OF) and cementifying fibroma. Under the 2017 WHO classification of odontogenic tumours and cysts, it is termed as cemento-ossifying fibroma. This lesion is commonest in the third and fourth decades of life with a female preponderance and commoner in the mandible than in the maxilla. In this article, we describe a rare case of COF presenting as an unusually large, diffuse lytic lesion in the mandible of a 28-year-old male patient.

Key words: Fibro-osseous lesion, cementum, mandible, osteoid
