慢性腎不全に合併した悪性腫瘍の3例

THREE CASES OF MALIGNANT TUMORS ASSOCIATED WITH CRONIC RENAL FAILURE

はじめに

　近年，透析療法および腎移植の進歩により，慢性腎不全患者の長期生存例が増加している。そのため，腎不全患者の悪性腫瘍合併が新たな問題となつてきた。そこでわれわれは，当施設における透析患者282例について悪性腫瘍の合併例を検討したところ，15例と高頻度（5.3％）であつた。このうち泌尿器悪性腫瘍は5例であつたが，最近の症例で，近年注目されているacquired cysticdiscase of the kidney　（以下ACDKと略す）の症例を2例，興味ある膀胱腫瘍の症例を1例経験したので報告する。

First case was a 45-year-old-woman who had renal cell carcinoma originated from acquired cystic disease of the kidney. The duration of hemodialysis was about 4.6 years before surgical operation.

The removed left kidney was 244 g in weight and numerous cysts up to 3 cm diameter were noted both in the cortex and medulla of the kidney. Those cysts were lined with cuboidal cells and papillary adenoma and solid adenoma arose from the lining epitherium of the cysts. Adjacent to the cyst of 3 cm diameter in the lower pole of the kidney, adenocarcinoma was found.
