“…The delay from onset of symptoms to accurate tissue diagnosis was 21 months, an improvement from the 2.8 years reported previously [27]. As in other studies [2,15] many of these tumours were initially diagnosed and treated as clinically benign swellings ( Table 1). The low level of awareness of this type of soft tissue tumour was confirmed by the significant proportion of large tumours (~5 cm max diameter) treated.…”

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.

“…Radiographs may be normal but up to 50% of cases show the presence of a nonspecific mass [ 5 ], 25% of tumours have areas of calcification, typically in the periphery of the lesion. Up to 20% of tumours may involve adjacent bone, evidenced as periosteal reaction, extrinsic erosion or aggressive osseous invasion.…”

This is a case of a 36-year-old gentleman with haemophilia A who was presented with an acute atraumatic soft tissue swelling in the right thigh. Open biopsy was performed with the resultant diagnosis of a synovial cell sarcoma. Although the clinical findings were nonspecific they could easily have been found in a bleeding haemophilic pseudotumour. The findings reported on MRI scan initially were highly consistent with those present in patients with mild haemophilia. An important part of orthopaedic management in haemophilia is concerned with intraarticular and intramuscular bleeding. Haematomas are common and sarcomas are rare. However the absence of trauma should alert the clinician to the possibility that the abnormality may represent haemorrhage into a tumour and not just haematoma, even in a haemophilic patient.

“…53,111,112 Patients with synovial sarcoma may initially present with a palpable slow-growing mass, which can simulate a benign process. 113 In contrast to most other soft-tissue malignancies, pain is often present. The duration of symptom may vary from days to as long as 20 years before initial diagnosis.…”
