ameloblastic fibrosarcoma
Monday 10 April 2006
Ameloblastic fibrosarcoma is a rare tumor and only the mesenchymal component shows features of malignancy but the epithelial compoment remains bland.
These tumors can occur de novo but can also be associated with recurrent ameloblastic fibroma or ameoloblastic fibroodontoma. There are usually no difficulties in recognizing the anaplastic features of the mesenchymal component.
It should be noted that in some cases, particularly those with multiple recurrences, the mesenchymal component can dominant the histologic picture and suggest fibrosarcoma or other types of sarcomas.
A high index of suspicion and diligent search for epithelial component is mandatory in order to make a correct diagnosis.
