Storiform pattern cells emanate from a central focusirregular fascicles, variable cellularity Pleomorphic and bizarre tumor cells with foamy cytoplasm and marked atypia, in background of inflamed collagenous stroma May represent end stage of various sarcomas with common morphologic features of pleomorphism and storiform growth pattern Multinucleated giant cells may be seen; if prominent, classify as MFH-giant cell Numerous mitotic figures, including atypical forms Rarely metaplastic not neoplastic bone or cartilage.

Soft Tissue Tumor Immunohistochemistry Update: The histopathology of the lesion was malignant adipose tissue tumour suggestive of dedifferentiated liposarcoma and the overlying skin being free from tumour.

A ljposarcoma lipomas are also referred to as well-differentiated liposarcomas and are believed to be low-grade tumors. Soft Tissue Tumor Immunohistochemistry Update: The histopathologic exam showed a well-differentiated liposarcoma with spindle and lipoma-like cells Grade 1without infiltration of the testis and with free surgical margins.
