Abstract
A 47years-old Japanese male was admitted to Kosei General Hospital with chief complaints of macroscopic hematuria and a right abdominal mass with pain. Cytological diagnosis was a renal cell carcinoma which was characterized by a group of adenocarcinoma cells with prominent pink nucleoli. He was operated on by a right nephrectomy 12 days after admission. Patho logical diagnosis of the resected kidney was a renal cell carcinoma with areas of cytoplasmic sudanophilia. Postoperative X-ray therapy (with a total dose of 2, 850 rads) was performed. Unfortunately he was scintigra phically found to have liver metastasis, and died 8 months after admission. Autopsy study revealed the xtensive metastasis of renal cell carcinoma to the lungs and the liver.
