To report a case of primary germ cell testicular tumor that spontaneously remitted after metastasizing to the retroperitoneum, leaving histologically characteristic lesions of a fused tumor. The characteristic testicular ultrasound findings that permitted the diagnosis are described.
METHODS/RESULTS: A 21-year-old male consulted for a retroperitoneal mass. The testes were normal on palpation. The testicular ultrasound showed a hyperechoic area with an acoustic shadow suspected as being a tumoral cicatrix. The histological analysis after orchidectomy revealed a mixed non-seminomatous germ cell tumor.
Testicular ultrasound evaluation should be performed on all patients with retrosperitoneal germ cell tumor and normal testes on palpation. In the case described, there was good correlation between the ultrasound and the histological findings.
报告一例原发性睾丸生殖细胞肿瘤，该肿瘤在转移至腹膜后后自发缓解，留下组织学特征性的融合肿瘤病变。描述了有助于诊断的特征性睾丸超声表现。
方法/结果：一名21岁男性因腹膜后肿块就诊。触诊时睾丸正常。睾丸超声显示一个伴有声影的高回声区，怀疑为肿瘤瘢痕。睾丸切除术后的组织学分析显示为混合性非精原细胞瘤性生殖细胞肿瘤。
对于所有腹膜后生殖细胞肿瘤且触诊睾丸正常的患者，均应进行睾丸超声评估。在所描述的病例中，超声与组织学结果之间具有良好的相关性。
