Poster Information
Abstract: 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, which was further confirmed immunohistochemically.Summary: a case report of hybrid central odontogenic fibroma showing giant cell reaction References: 1.
