Synovial sarcoma (SS) is a rare malignant mesenchymal tumor mainly arising in the peri-articular tissue in young adults. There are few cases reported in other areas. A 26-year-old woman presented with a palpable abdominal mass. USG abdomen showed evidence of an ill defined, multi lobulated mass lesion seen in the peritoneal cavity on left side. Based on histopathological and immunohistochemical (IHC) examination a diagnosis of Synovial sarcoma was given. A synovial sarcoma should always be considered in the differential diagnosis, and immunohistochemistry is an important adjuvant tool in this situation. We report a rare case of primary synovial sarcoma arising in the mesentery.
