 To investigate the distribution of tumour cells expressing the SYT-SSX fusion gene in biphasic synovial sarcoma, modified reverse transcription polymerase chain reaction (RT-PCR) analysis was performed using microdissected specimens from haematoxylin and eosin stained sections of archival paraffin wax embedded tissues.     ///    "These results indicate that SYT-SSX fusion transcripts are found in both epithelial and spindle cell areas of biphasic synovial sarcoma, and RT-DOP-PCR-PCR analysis is a useful method for detection of extremely small amounts of mRNA in microdissected samples from archival formalin fixed, paraffin wax embedded tumour tissues.. "    ///    Detection of SYT-SSX fusion transcripts in both epithelial and spindle cell areas of biphasic synovial sarcoma using laser capture microdissection..     ///    SYT-SSX fusion transcripts were detected in both epithelial and spindle cell areas of all three biphasic synovial sarcomas examined.
