Soft tissue recurrence of osteoclastoma

We report a case of osteoclastoma of the distal radius originally treated by curettage, then by resection and bone replacement. There was a soft tissue recurrence of the tumor 13 years later.     

空泡型质子泵在骨巨细胞瘤多核巨细胞中表达

通过电镜观察附着于骨片的骨巨细胞瘤多核巨细胞，表明在骨吸收时具有褶皱缘结构。采用可标记破骨细胞褶皱缘的空泡型质子泵３１ＫＤ亚基的抗体，对体外培养的骨巨细胞瘤细胞进行免疫组织化学染色，结果显示多核巨细胞为阳性，间质细胞为阴性，阳性区主要分布于多核巨细胞浆内的空泡区及伪足区。通过ｍＲＮＡ原位杂交方法检测到，多核巨细胞和间质细胞中均有空泡型质子泵的３ｌＫＤ亚基ｍＲＮＡ表达。结果提示多核巨细胞与破骨细胞可能有相似的骨吸收泌酸机制。     

Giant cell tumor (osteoclastoma): a case report]

The history is presented of a 21-year-old woman with an osteoclastoma (giant cell tumour) which was treated with total local excision and an elbow prosthesis. A 5-year follow-up report, the problems of treatment and the different grades of malignancy, are discussed briefly, and the value of histological grading is shown.     

Vertebral thoracic osteoclastoma a case report with emphasis on roentgenological findings

Summary A rare case of vertebral osteoclastoma in the body of T₈ is presented. Attention is drawn to its unusual radiological features, not previously reported, and to the relative inefficiency of radiotherapy.The most rational treatment for such a tumour appears to be the widest surgical decompression possible, followed by low-dose irradiation.     

Giant cell tumor (osteoclastoma) of the petrous bone: case report

A case of a basal middle fossa giant cell tumor occurring in a 46-year-old man is described. The lesion appeared at the computed tomography (CT) scan examination as an hypodense mass with a peripheral "ring-like" enhancement, and no evident erosion of the skull base. The tumor, which infiltrated the basal temporal parenchyma, was removed via a temporal transzygomatic craniotomy, and extensive drilling of the petrous bone. Despite the occurrence, of significant postoperative complications, the patient ultimately showed a good clinical outcome, with no signs of recurrence at the 1-year follow-up CT scanning. The clinical and diageostic aspects and the management policy, of this rare lesion are discussed.
