Unusual presentation of synovial sarcoma of Iliotibial band- A Case Report

Unusual presentation of synovial sarcoma of Iliotibial band

Abstract

Synovial sarcoma is a rare soft tissue tumour which usually manifest as pain followed by swelling. We present two cases with unusual presentation of synovial sarcoma with limp with abduction deformity of hip.
Two cases of 7 year old boy and 13 year old girl presented identically with painful limp. Tenderness was present on anterolateral aspect above the knee joint and fixed abduction deformity of ipsilateral hip joint was noted. Bone scan was normal and MRI revealed soft tissue swelling arising from lateral aspect of distal thigh. On exploration, soft tissue tumor was arised from iliotibial band and biopsy revealed monophasic fibrous type of synovial sarcoma. Immunohistochemistry confirmed the same.
Orthopaedic surgeon must be aware about unusual presentations of symptoms and site of origin to prevent unnecessary delay in diagnosing rare highly malignant tumor
