[Liposarcoma of the pancreas. Study of a case including ultrastructure].
The authors report a case of polymorphous liposarcoma situated in the pancreas. Ultrastructural study of proliferation demonstrated two cell contingents which appeared to represent stages of varied differentiation in the elaboration of adipose cells. The marked preponderance in the case studied of clear and little organised cells would appear to justify the histological classification of the polymorphous liposarcoma as a relatively undifferentiated tumour. Furthermore, this study emphasised the value of electron microscopy in the diagnosis of neoplasms which are complex from a morphological standpoint.
