title: Nonpalpable occult testis tumor.
abstract: We present a case study of a patient with seminoma who had normal testicles on palpation. Testicular ultrasound is the technique of choice to locate occult nonpalpable testis lesions. We recommend its use in the search for the source of any retroperitoneal mass of undetermined origin.
