Prevalence of Carcinoma in Situ and other Histopathological Abnormalities in Testes From 399 Men who Died Suddenly and Unexpectedly

Abstract
To determine the prevalence of carcinoma in situ of the testis and other testicular histopathological abnormalities in the general male population, we examined gonads from 399 men 18 to 50 years old who died suddenly and unexpectedly. No sign of malignancy was found in any of these gonads. However, 3 of the 399 men had been previously treated for testicular tumor or carcinoma in situ. Thus, the over-all prevalence of testicular neoplasia in the population studied was 0.8% (95% confidence limits 0.2 to 2.2%). This frequency is of the same magnitude as the lifetime risk of testicular cancer in the Danish male population.
