The occurrence of giant cell tumors in the pelvis is unusual, and accounts for only 1.5~6% of all giant cell tumors in bones. Between 1992 and 1999, five patients with pelvic giant cell tumors were diagnosed and managed at our institution. One patient received wide excision with hemipelvectomy while the other four patients received intralesional excision with allograft reconstruction. One patient who had residual tumor after operation received external beam irradiation. All patients were free of local recurrence at a mean follow-up of 92 months (range: 74-115 months). Postoperatively, palsy of sciatic nerve occurred in one patient but no other complications, such as wound infection or fracture, were seen. The nerve palsy recovered completely one year later. These results demonstrate that intralesional excision with adjuvant therapy is a feasible treatment approach for the management of giant cell tumor of the pelvis and results in a positive outcome.
