Testicular microlithiasis: case report and discussion of management under special consideration of testicular germ cell tumours.

We report a case of testicular microlithiasis in a 24-year-old man who was referred to us for evaluation of unclear ultrasonographic appearance of his testes while being examined for bilateral varicocele and epididymal cysts. Since testicular microlithiasis has been found to be associated with testicular germ cell tumours we suggest a diagnostic work-up with testis biopsy to rule out testicular intraepithelial neoplasia (so-called carcinoma in situ) in otherwise normal appearing testis.
