Diagnosis of recurrent synovial sarcoma by fine needle aspiration cytology--a case report.

Cytodiagnosis of synovial sarcoma can be a daunting task, owing to the varied cytomorphological appearances possible, depending on whether the tumour is monophasic or biphasic in architecture. We report herewith a case of recurrent synovial sarcoma in a young male who presented with a swelling in the neck. The diagnosis was established by fine needle aspiration cytology.
