title: Synchronous multicentric giant cell tumor.
abstract: Multicentric giant cell tumors represent less than 1% of all giant cell tumors of bones. We report a case of multicentric giant cell tumors around both the knee joints in a mentally and physically challenged adult male that resulted in rapidly progressive painful swelling, restricted mobility and, ultimately, fixed deformity. These tumors had typical radiological appearance and the diagnosis was confirmed on histopathology.
