Well-Differentiated Spindle Cell Liposarcoma (Atypical Spindle Cell Lipomatous Tumor).--This entity is a recently reported [CD34.sup.+] low-grade malignant lipogenic neoplasm that shares some similar histologic and molecular features as SCL.
Dei Tos et al[10] have reported the histologic findings of spindle cell liposarcoma. While none of their cases described FNA findings, the authors pointed out that spindle cell lipoma can be distinguished from spindle cell liposarcoma by abundant normal fat cells, extremely bland palisaded spindle cells, eosinophilic refractile collagen bundles, and the absence of an infiltrative pattern in the former.
In 2002; WHO has classified well-differentiated liposarcoma into four subtypes as adipocytic (or lipoma-like), sclerosing, inflammatory, and spindle cell liposarcomas; in which commonest is adipocytic or lipoma-like liposarcoma where proliferation of relatively mature adipocytes found (11).
