"Immunohistochemistry stains might be positive for S100, CD99, SOX9 and vimentin 1,4. Smooth muscle actin, GFAP and keratins are typically negative 1."
"The tumour is also negative for FLI-1, which can be helpful in the differentiation from Ewing sarcoma 1,5. Expression of SMARCB1 (INI-1) is retained which can be helpful for the differentiation from other soft tissue tumours including extraskeletal myxoid chondrosarcoma, epithelioid sarcoma and myoepithelial carcinoma 1,5."
"Mesenchymal chondrosarcomas are characterised by HEY1-NCOA2 rearrangements 1,6."
