AMELOBLASTIC FIRBO-ODONTOMA ASSOCIATED WITH CALCIFYING ODONTOGENIC CYST – A CASE REPORT & REVIEW OF THE LITERATURE

Hybrid odontogenic tumours are rare and present with numerous histopathological patterns. Odontogenic tumours su ch as ameloblastoma, ameloblastic fibroma (AF), ameloblastic fibro-odontoma (AFO), and odontoma are uncommonly found in conjunction with odontogenic cysts such as calcifying odontogenic cyst (COC), glandular odontogenic cyst (GOC), and odontogenic keratocyst. The case of a 19-year-old female patient with an expansile, bony hard swelling connected with the left posterior maxilla is presented. It was showing mixed radiopaque and radioluent nature. Histologically, on incisional biopsy, it was found to be an ameloblastic fibroodontoma. After complete excision of the lesion, along with an ameloblastic fibroodontoma it was also associated with a cystic fluid filled cavity which on microscopic examination was found to be a Calcifying odontogenic Cyst. We believe it is important to report COC with AFO with full clinical and pathological evidence because there are few examples of COC with AFO cited in the English literature.
