Cytokeratin-negative epithelioid sarcoma: a case report
IntroductionEpithelioid sarcoma (ES) is a rare,soft tissue sarcoma,which was first described by Enzinger in 1970”1”.It predominantly arises in the extremities of young adults,and lymphatic spread is common,which is unlike other sarcomas.Immunohistochemistry has already been proven to be conclusive in supporting morphological findings and in identifying histological subtypes.Co-expression of vimentin,cytokeratin (CK)and epithelial membrane antigen (EMA) are the immunohistochemical characteristics”2”.Here,we report a patient with negative staining of pan-CK,CK 5/6 and CK A1/A3.
