<prompt> Synovial sarcoma cellular markers are -a Cytokeratinb S-100c Vimentind Calretininabcbcacdbcd  <response>: Immunohistochemistry: these tumors have spindle cells which are positive for vimentin and epithelial components positive for cytokeratin. More recently, molecular diagnostic studies have identitied a unique translocation, t X;18, producing SYTSSX1 or - SSX2 fusion genes. S-100 staining may give positive results.
