A CASE OF AMELOBLASTIC FIBROSARCOMA

Ameloblastic fibrosarcoma (AFS) is a rare odontogenic tumor comprising a benign epithelial component and a malignant ectomesenchymal component. AFS is a neoplasm with a similar structure to the ameloblastic fibroma, but in which the mesodermal component shows the features of a sarcoma. Here we present a case of ameloblastic fibrosarcoma of mandible in a 32 year old male patient for whom the pre operative incisional biopsy was diagnosed as ameloblastic fibroma. In histopathology of resected specimen some mesenchymal areas showed distinct cellular pleomorphism of an anaplastic sarcoma. So this may be due to recent transformation of ameloblastic fibroma to fibrosarcoma.
