Giant Cell Tumor of Patella-Common Tumor in Uncommon Location

Abstract

Giant cell tumors comprise approximately 4% of all bone tumors. Usually GCT occurs as eccentric epiphyseal lytic lesion in a mature skeleton, commonly along the long bones. Uncommonly they are seen to occur in calcaneus, ribs, carpal bones and patella. We report a case of Giant Cell Tumor of Patella in an 18 year old male presenting with history of pain and swelling of right knee. The diagnosis was made on radiologic investigations and was confirmed on histopathological examination.
