Abstract
We encountered a hemodialysis patient with sarcomatoid renal cell carcinoma. The patient was a 58-year-old male, who had been on hemodialysis for 23 years. He was admitted to the hospital because of a high level of C-reactive protein. In June 20xx, we found masses in his livers in computed tomography (CT) images, but could not idenfy the primary site of the tumor. His condition rapidly deteriorated, and he finally died on the 96th hospital day. Autopsy demonstrated right renal cancer as well as metastatic tumors in the liver, spine, and peritoneal membrane. Pathologically, we diagnosed sarcomatoid renal cell carcinoma (RCC) arising from the right kidney mass. It is well-known that RCC occurs in hemodialysis patients. To diagnose this disease in the early stage, regular examinations are essential, but, in sarcomatoid renal cell carcinoma, renal tumors remain difficult to diagnosis correctly, even with CT images. Further examinations are necessary to develop a plan for screening or therapy for sarcomatoid renal cell carcinoma.
