RESUMO
Ameloblastic fibrodentinoma (AFD) is a rare benign tumor usually interpreted as a neoplasm similar to ameloblastic fibroma (AF), characterized by formation of dysplastic dentin on histopathological diagnosis. Peripheral –type ameloblastic fibro-dentinoma (PAFD) is exceedingly rare, with all previously reported cases involving young patients. We here report a case of PAFD occurring in upper gingiva of an 11-year old male child, which was surgically incised.
RESUMO
Odontogenic tumors comprise a complex group of lesions of diverse histopathological types and clinical behavior. The group of mixed odontogenic tumors, which are also rare, is composed of proliferating odontogenic epithelium in a cellular ectomesenchyme resembling dental papilla. Ameloblastic fibrodentinoma is a rare benign odontogenic tumor. The present case report discusses this tumor composed of odontogenic epithelium and odontogenic mesenchyme with dentin or dentin like tissue. The present paper also throws light on various histological similarities and complexities which make the interpretation of these set of odontogenic tumors a diagnostic dilemma.
