再發한 巨大細胞腫 2例 = Two Cases of Recurrent Giant Cell Tumor of Bone

다국어 초록 (Multilingual Abstract)

Two cases of recurrent giant cell tumor of bone which involved the distal end of the right femur of a 33 year old male and the proximal end of the right femur of a 39 year old male are presented.
Clinical signs, symptoms, roentgenographic findings, and bone biopsy led to the diagnosis.
The primary lesions of these cases were treated by curettage and autogenous bone grafts. Recurrence of one case of the lesion was clinically noted six months after . the primary operation, and the other four months after the primary operation.
The recurrent lesion showed more trabeculation in roentgenography, and had more stromal cells, fewer giant cells, and had smaller sized giant cells compared to the primary lesions.
One of the cases refused to have the amputation, so the pathological fracture was treated by open reduction and internal fixation and discharged from the hospital.
The' other case had a right hip disarticulation, and the postoperative course had been uneventful.
Three months later he was discharged from the hospital with a hip disarticulation prosthesis.
There has been no evidence of recurrence or malignant change during the two year postoperative course in case II.
