title: [A case of metachronous bilateral testicular tumors with burned-out histology in one side].
abstract: A 22-year-old man with a history of left radical orchiectomy due to a testicular tumor had bilateral pulmonary tumors. Transbronchial biopsy specimens revealed them to be germ cell tumors. The serum levels of AFP and hCG-beta were elevated. The right testis was free from a palpable mass but showed a small hyperechoic lesion on scrotal ultrasonography. We excised the echogenic focus, which was a whitish nodule under the tunica albuginea. By pathological findings it was diagnosed as a burned-out testicular tumor. This was a case with metachronous bilateral testicular tumors.
