Abstract
A case with large intra-abdominal monophasic synovial sarcoma has been described. Ultrasonography revealed a large tumor having both solid and cystic areas. Exploratory laparotomy revealed that the tumor was arising from the omentum. Microscopic examination showed proliferation of spindle cells. Immunohistochemical (IHC) examination showed strong positivity for Vimentin, CD99 and Bcl-2. Focal positivity for cytokeratin was also seen. Result of FISH indicated break at SYT region. Findings were suggestive of a monophasic fibrous synovial sarcoma.
Keywords: Monophasic mesenchymal malignant neoplasm
