Clear cell sarcoma (CCS) of the tendons and aponeuroses is a rare soft tissue sarcoma that morphologically resembles cutaneous malignant melanoma but exhibits a distinct molecular profile. Gastrointestinal (GI) CCS is extremely rare. In this study, two cases of CCS were presented: (1) left thumb and (2) jejunum. Case 1 manifested the characteristic CCS morphology. Case 2 was morphologically unusual and difficult to diagnose. Immunohistochemically, the two cases of tumor cells were diffusely positive for S100, vimentin, NSE protein, focal expression of CgA, and CAM2.5 protein. In case 1, the tumor cells were diffusely positive for HMB45, focal expression of CD56, and melan A antigen. Reverse transcriptase-polymerase chain reaction (RT-PCR) results confirmed the presence of the EWS/ATF1 translocation (type 1) in the two cases. Then, we detected 19 hotspot oncogenes in the two cases. To the best of our knowledge, this study is the first to apply a high-throughput OncoCarta panel 1.0 and MassARRAY system to detect 238 known mutations in 19 hotspot oncogenes in soft tissue clear cell sarcoma. In this study, no mutations were observed in these hotspot oncogenes in the two cases.
