Abstract: Poorly differentiated synovial sarcomas are diagnostically challenging soft tissue tumors. They can be indistinguishable from other
“small blue cell tumors” based on morphology and even immunohistochemical studies. Here we report a rare case of poorly differentiated
metastatic synovial sarcoma to lung without known primary, diagnosed with molecular genetic analysis. The tumor was negative for EMA and
cytokeratin, previously reported as the most sensitive immunostaining markers for synovial sarcomas. SYT-SSX gene fusion, characteristic for
synovial sarcoma, was identified in this case by FISH and RT-PCR assays. (IJCEP903004).
Key words: Synovial sarcoma, lung, metastatic, molecular genetic
