Abstract
The authors report the case of a 26-year-old man who was operated upon for bilateral testicular maldescent when he was 11 years old. In a follow-up examination for men with a history of orchiopexy for cryptorchidism, he palpated a dense nodule emerging from his right testis, and therapy for invasive testicular cancer was started. The histologic diagnosis was a mixed teratoma consisting of yolk-sac tumor, differentiated teratoma, and embryonic carcinoma. We conclude that young men with a history of testicular maldescent should be followed up by a multidisciplinary approach and should be offered testicular biopsy after puberty to allow detection and treatment of testicular intraepithelial neoplasia (so-called testicular carcinoma in situ) to prevent invasive testicular cancer.
