Biology:Lipoblast
A lipoblast is a precursor cell for an adipocyte.[1]
Alternate terms include adipoblast[2] and preadipocyte.[3]
Early stages are almost indistinguishable from fibroblasts.[4]

Histopathology of liposarcoma, H&E stain, with the main features:[5]
- Spindle cells with enlarged, hyperchromatic nuclei.
- Apparently univacuolated adipocytes (may look normal).
- Lipoblasts (multivacuolated), but neither necessary nor sufficient for diagnosis of liposarcoma.
Liposarcoma
Lipoblasts are seen in liposarcoma[6] and characteristically have abundant multivacuolated clear cytoplasm and a dark staining (hyperchromatic), indented nucleus.
