The second primary prostatic synovial sarcoma was confirmed using molecular analysis. Reverse transcriptase polymerase chain reaction (RT-PCR) identified the SYT-SSX gene fusion, aiding diagnosis.

Area of Science:

  • Oncology
  • Molecular Pathology
  • Genetics

Background:

  • Primary prostatic synovial sarcoma is exceedingly rare.
  • Diagnostic challenges arise from atypical morphology and non-specific immunohistochemistry.

Observation:

  • The tumor exhibited spindle-cell and poorly differentiated round-cell morphologies without epithelial differentiation.
  • Immunohistochemical staining provided inconclusive results.

Findings:

  • Molecular confirmation was achieved through reverse transcriptase polymerase chain reaction (RT-PCR).
  • The characteristic SYT-SSX gene fusion specific to synovial sarcoma was identified.

Implications:

  • This case highlights the critical role of molecular techniques in diagnosing challenging tumors.
