Fibrosarcoma arising in DFSP - DFSP cells trap fat cells, fibrosarcoma cells are more uniform

Fibrosarcoma cells are spindled, uniform and hyperchromatic and arranged in herringbone pattern

Pleomorphc, tumor cells are pleomorphic and have granular chromatin

Uncommon finding is hyoid nodules
containing cells with eosinophilic cytoplasm,
present in DFSP or fibrosarcomatous areas,
cells are actin+, CD34-, desmin-
