Abstract

INTRODUCTION: Multicentric Giant Cell Tumor is extremely rare; here we are presenting a case of pathological neck femur fracture in case of multicentric giant cell tumor involving ipsilateral acetabulum along with femoral head and neck. CASE PRESENTATION: 24 years old male presented with pain in groin region and inability to walk after he fell down while walking. He had pain in left groin on weight bearing for last six months. Radiological examination shows pathological trans-cervical femoral neck fracture with sub-articular lytic lesion in femoral head and neck suggestive of Giant cell tumor. MRI has been done to define the extent of involvement and to rule out soft tissue infiltration. Fine needle aspiration cytology which was done through anterior route was inconclusive. After review of literature, patient has been planned for excisional biopsy and un-cemented total hip arthroplasty. Intra-operatively, frozen section confirms the giant cell tumor and surprisingly acetabulum was found to be involved which was curetted and hydrogen-peroxide treated. Post-operatively, patient was pain-free with good range of movements at hip. CONCLUSION: Giant cell tumor involving femoral head and neck with pathological fracture though uncommon, but may present as multicentric with acetabular involvement.
