"SMARCB1/INI1 loss"
"Epithelioid sarcomas are associated with mutations of the SMARCB1 or INI1 gene resulting in a loss of SMARCB1 nuclear protein expression 1."
"Immunohistochemistry stains of both subtypes are usually positive for epithelial membrane antigen (EMA), vimentin and cytokeratins including CK8 and CK19 but are often negative for CK5/6. More than half of the cases show positivity of CD34 and predominantly the classic subtype shows reactivity to ERG in a fair number of cases 1,2."

"Signal characteristics"
"Epithelioid sarcomas are malignant usually slow-growing mesenchymal tumours of unknown and multidirectional differentiation. There are classic and proximal subtypes."
"Epithelioid sarcomas are rare and make up for"
"There are two accepted subtypes of epithelioid sarcomas 1:"
"MR imaging features of epithelioid sarcomas are non-specific and feature inhomogeneous variable patterns due to variable amounts of necrosis, haemorrhage and granulomatous areas 3-6. Multiple soft tissue nodules possibly associated with ulcers should raise suspicion of this entity 4."
