atypical lipomatous tumour

(redirected from spindle cell liposarcoma)

atypical lipomatous tumour

A well-circumscribed, low-grade malignancy which arises in deep soft tissue of extremities, retroperitoneum, and groin, for which the term “well-differentiated liposarcoma” is increasingly preferred. As a general rule, the deeper the tumour, the more likely it is to recur.
Management Complete excision is curative.

Well-Differentiated Spindle Cell Liposarcoma (Atypical Spindle Cell Lipomatous Tumor).
Well-differentiated spindle cell liposarcoma ('atypical spindle cell lipomatous tumor') does not belong to the spectrum of atypical lipomatous tumor but has a close relationship to spindle cell lipoma: clinicopathologic, immunohistochemical, and molecular analysis of six cases.
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.
