Primary synovial sarcoma of the lung: report of two cases confirmed by molecular detection of SYT-SSX fusion gene transcripts..     ///    "In both cases, a reverse transcription-polymerase chain reaction using RNA extracted from formalin-fixed, paraffin-embedded tissues detected SYT-SSX fusion gene transcripts, which are characteristic of synovial sarcoma. "    ///    Our molecular assay detecting the SYT-SSX fusion transcripts is useful for the final diagnosis of synovial sarcoma arising at such an unusual anatomical site..
