Ameloblastic fibroma and ameloblastic sarcoma–a report of the cases, histopathology and histochemistry. It is critical to differentiate AFS, especially low-grade variant, from ameloblastic fibroma, and recently, several immunohistochemical studies with Ki67, Bcl-2, PCNA, c-KIT, and P53 have been performed, suggesting that proliferating markers in association to histopathologic features could be useful for identifying the malignant tumor.

Bruns Beitr Klin Chir ; Therefore, also considering epithelial component, the diagnosis based on histopathological examination was not a serious problem. In a few described cases, adjuvant chemotherapy was used, with inconclusive results 4. As expected, the pain persisted and healing of the extraction site was not normal.

However, adjuvant radiotherapy was also performed in order to ensure a better outcome. Because of rarity of cases, it is almost impossible to estimate long-term prognosis accurately and many patients have died from uncontrolled local invasive disease.
