Atypical Spindle Cell/Pleomorphic Lipomatous Tumor

Preferred Label : Atypical Spindle Cell/Pleomorphic Lipomatous Tumor;

NCIt synonyms : Fibrosarcoma-Like Lipomatous Neoplasm; Spindle Cell Liposarcoma; Atypical Spindle Cell Lipoma;

NCIt definition : A benign adipocytic neoplasm, characterized by ill-defined tumor margins and the presence of variable proportions of mild to moderately atypical spindle cells, adipocytes, lipoblasts, pleomorphic cells, multinucleated giant cells, and a myxoid or collagenous extracellular matrix. It has a low tendency for local recurrence if incompletely excised. Unlike conventional atypical lipomatous tumors, there is no risk for dedifferentiation. (WHO 2020);

Neoplastic status : Benign;
