title: Ultrasound in detection of early neoplasia of the testis.
abstract: Testicular ultrasound scanning was performed in 192 men with a history of cryptorchidism. The ultrasonic tissue pattern was evaluated and each testis was accordingly given a score on a scale from 1 to 4, 1 representing the normal uniform pattern and 4 being a very irregular pattern. Testicular biopsy of the previously maldescended testicle(s) was carried out in 143 of the scanned men and from two contralateral testicles where the score 4 was given at the ultrasound examination. Two biopsies showed carcinoma-in-situ pattern. Both were found among testes with a very irregular echo pattern. This pattern was found in only 3.2% of all scanned testes.
