Central Odontogenic Fibroma with Giant Cell Granuloma-Like Lesion: A Report of an Additional Case and Review of Literature.

Central odontogenic fibroma is a rare benign odontogenic tumor that relies on clinical-radiographic-histological correlation to reach its diagnosis, especially its rare variants. Of these rare types is the coexistence of giant cell granuloma-like lesion, with the characteristic odontogenic epithelial rests. The presented case is a 33 years old female complaining of asymptomatic mandibular bony swelling. Radiographically, the lesion is unilocular radiolucent, without root resorption. Histological examination revealed the presence of multinucleated giant cells within the diagnosed central odontogenic fibroma. Immunohistochemical staining highlighted the presence of both components.
