Synovial sarcoma: a clinicopathological review.

We have reviewed 20 cases of synovial sarcoma. The main clinical and pathological features of these cases are outlined. Typically these tumours arise in the leg in young adults with a long history before presentation and diagnosis. Clinical and radiological findings are unhelpful in making an early diagnosis. The five year survival rate in this series was 43%. The best guide to prognosis was assessment of mitotic activity. A high index of suspicion is required if the diagnosis is not to be missed. Adequate wide excision of the tumour is the mainstay of treatment.
