Giant cell tumour (GCT) of bone also known as osteoclastoma is a distinct clinical, roentgenographic and pathologic entity having specific characteristics. It is a benign but locally aggressive neoplasm. Classically it is seen as a purely lytic lesion of the epiphyseal or metaphyseal-epiphyseal region of long tubular bones. The most common locations include the distal femur, proximal tibia and distal radius. We report here a case of 25 years old lady presented with a swelling over right lower lateral part of chest wall with a provisional diagnosis of primitive neuro ectodermal tumour (PNET). Computed Tomography (CT) report showed destruction of right tenth rib antero-laterally with soft tissue density lesion. The biopsy revealed giant cell tumour of rib composed of regular distribution of large sized giant cells in a background of benign appearing stromal cells. This type of tumour on the anterior arc of the rib is a very rare occurrence. Even though occur in ribs, it usually occurs in the posterior aspect and quite often the diagnosis is delayed. The patient underwent complete primary resection of the tumour and bone grafting with amelioration of symptoms. Her post operative 2 years follow up is uneventful. So we want to highlight through this rare case that chest wall GCT should be included in the differential diagnosis of any chest wall masses.
