Osteoclast-like giant cell tumors are rare mesenchymal tumors that typically present in osseous tissue and are remarkable because of their slow growth. We report the sixth documented case of a malignant osteoclast-like giant-cell tumor primary to the kidney of an 81-year-old man with a 5-month history of hematuria. Postnephrectomy analysis of the tumor, including immunohistochemical stains and electron microscopy, confirmed the diagnosis. Although the patient died of unrelated complications, metastatic disease was suspected.
破骨细胞样巨细胞瘤是罕见的间充质肿瘤，通常出现在骨组织中，因其生长缓慢而显著。我们报告了第六例有记录的原发性肾恶性破骨细胞样巨细胞瘤，患者为一名81岁男性，有5个月血尿病史。对肿瘤进行肾切除术后分析，包括免疫组织化学染色和电子显微镜检查，确诊了该病例。尽管患者死于无关并发症，但怀疑有转移性疾病。
