Abstract
A case of primary synovial sarcoma of the jejunum was collected and analyzed retrospectively. A 19-year-old man who presented to hospital with abdominal pain. The CT scan showed a large mixed abdominal mass with bleeding. Laparotomy revealed that the tumor originated from the jejunum, accompanied by rupture and hemorrhage. Microscopically, the tumor was composed of spindle cells. The tumor cells demonstrated diffuse expression of vimentin, transducin-like enhancer (TLE)-1, B-cell lymphoma protein (Bcl)-2, CD99 and focal expression of epithelial membrane antigen (EMA). The presence of specific SS18 gene rearrangement was confirmed in tumor cells. The patient received 6 cycles of chemotherapy after jejunal tumor resection. And 12 months later, the patient presented pancreatic metastasis and had radiotherapy. The patient died 15 months after the diagnosis.
