滑膜肉腫の2例

抄録

Two cases of synovial sarcoma were reported. The first case was developed in the anterior aspect of the hip joint in a 32-year-old-male. It adhered to the joint capsule and was removed marginally. Regional radiotherapy was employed, but the patient died by the metastasis 11 months after surgery. The tumor measured 5×5×4.5cm and was classified as group C histologically (MacKenzie). Second case was developed in the distal end of the upper arm in a 61-year-old-male. A marginal excision was performed, but local recurrence developed 2 years later. A disarticulation of the shoulder joint was carried out and postoperatively, 0.4-0.6mg/kg of Adriamycin was administered for two days in every four weaks. Six months after surgery, the patient is free of disease. The primary tumor measured 5×4×3.5cm and classified as group B. The recurrent tumor extensively invaded the humerus and was classified as group C.
