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]

Liposarcoma
[edit]Lipoblasts are seen in liposarcoma[7] and characteristically have abundant multivacuolated clear cytoplasm and a dark staining (hyperchromatic), indented nucleus.
