- Spindle cells with enlarged, hyperchromatic nuclei.
- Apparently univacuolated adipocytes (may look normal).
- Lipoblasts (multivacuolated), but neither necessary nor sufficient for diagnosis of liposarcoma.

Reference for findings:


Liposarcoma

Lipoblasts are seen in liposarcoma and characteristically have abundant multivacuolated clear cytoplasm and a dark staining (hyperchromatic), indented nucleus.
