Experience of screening for carcinoma‐in‐situ of the testis among young men with surgically corrected maldescended testes

Abstract

One hundred and twelve young men with maldescended testes which had been surgically corrected were examined for premalignant/malignant changes in the testes. Bilateral testicular biopsies were made in ninety-four patients. Three had carcinoma-in-situ of the testis in the biopsy. Invasive tumour of seminomatous type was found in two of these testes after orchidectomy had been performed. No correlation was found with testicular localization pre- or postoperatively, with testicular volume or with tumour markers.
