| Summary: |
Ameloblastic fibrosarcoma (AFS) is a rare malignant tumor characterized by benign epithelial component within a malignant fibrous stroma. It occurs as a de novo lesion or from a previous ameloblastic fibroma. The aim of this paper is to report an aggressive and recurrent case of AFS in the maxilla of a 38-year-old patient. Histopathological diagnosis can be challenging, especially when it is based on incisional biopsy specimens. Hence, this report highlights not only the importance of the histological features for diagnosis but also the clinical behavior of AFS based on current literature evidence. |
