Fine Neddle Aspiration Cytology of Myxoid Liposarcoma with Round Cell and Dedifferentiated Component: A Case Report Arising in Perirenal Area

The application of the fine needle aspiration(FNA) cytology to the soft tissue tumors has been used increasingly in the preoperative diagnosis of these tumors due to its usefulness and accuracy.

We present a case of liposarcoma, showing mosly myxoid component, but small portions of round cell and dedifferentiated component, diagnosed by FNA cytology with histologic confirmation. Good correlation between histologic and FNA cytologic findings was found. Although the cytologic appearances of liposarcomas varied with histologic type, the main criterion was the presence of atpical multivacuolated lipoblast with characgteristically scalloped nuclei.
