再発を繰り返した大腿悪性線維性組織球腫の治療経験

抄録

Patient was a 56-year-old man with a soft tissue tumor of left thigh.
Since 1969 to 1979, patient was operated eight times because of local recidivum without metastasis. Pathological diagnosis was Liposarcoma primarily, but it was changed three times as malignant mesenchymal tumor, malignant schwannoma and malignant fibrous histiocytoma.
In October 1979, he admitted for recidivum of tumor. In roentgenogram, bony invasion from soft tissue tumor was seen but there was no metastasis in other organs. Radical en bloc resection was performed to avoid amputation. Bone cement, autograft of fibula and intermedular nail were used to fill the defect of tumor. The final pathological diagnosis was malignant fibrous histiocytoma of soft tissue.
Patient showed good functional recover but five months after operation the inter medurally nail was broken by stress. Because reconstructive surgery seemed to be impossible, we had to amputate his lower limb from hip joint.
