title: Testicular neoplasm diagnosed by ultrasound.
abstract: The diagnosis of testicular cancer is usually made by the findings of a testicular mass on physical examination. In rare cases a young man will present with retroperitoneal nodes and a normal testicular examination. In such cases a testicular ultrasound may localize the testis which harbors a subclinical neoplasm. In addition serum markers of B-HCG and AFP are essential. As a screening procedure a urine pregnancy test is helpful, since it can be obtained quickly while quantitative B-HCG and APF results are delayed.
