CASE-REPORT - CYSTIC-FIBROSIS AND EMBRYONAL CARCINOMA OF THE TESTIS

The authors describe a patient with cystic fibrosis and a stage III te sticular embryonal cell cancer. Because cystic fibrosis occurs in appr oximately 1 of 2,500 births and embryonal carcinoma in 3 of 100,000, t he likelihood of concurrence for both disorders in the same patient is approximately 1 in 80 million. Involvement of the vas deferens in cys tic fibrosis raises the possibility of a fundamental embryologic basis that explains the pathogenesis of this association.
