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.
一名22岁男性，因睾丸肿瘤行左侧根治性睾丸切除术，现双侧肺部出现肿瘤。经支气管活检标本显示为生殖细胞肿瘤。血清甲胎蛋白（AFP）和β人绒毛膜促性腺激素（hCG-β）水平升高。右侧睾丸未触及肿块，但阴囊超声检查显示有一个小的高回声病变。我们切除了这个高回声病灶，它是白膜下的一个白色小结节。根据病理结果，诊断为消退型睾丸肿瘤。这是一例异时性双侧睾丸肿瘤病例。
