[Hypernephroid carcinoma and carcinoma of the urinary tract following phenacetin abuse]

From the 24 683 autopsies performed at the Institute of Pathology of Zurich University from 1963 to 1973, all cases with hypernephroid carcinoma or carcinoma of the urinary tract were listed. For each type of carcinoma the extent of phenacetin abuse, the sex and the mean age of the patients were established. The positive relationship between phenacetin abuse and carcinoma of the renal pelvis and the urinary bladder confirms the results of other investigators. In addition, a relationship between phenacetin abuse and hypernephroid carcinoma is discussed.
