We report a case of seminoma of the testis metastatic to the retroperitoneum. Biopsy of the retroperitoneal mass revealed anaplastic seminoma. No testicular mass could be palpated. Testicular ultrasonography showed a hypoechoic 3 X 2 cm. area in the left testis suggestive of a primary testicular tumor, most likely a seminoma. Histological evaluation of the resected testis revealed fibrous tissue but no definable tumor.
我们报告一例睾丸精原细胞瘤转移至腹膜后。腹膜后肿块活检显示为间变性精原细胞瘤。未触及睾丸肿块。睾丸超声检查显示左侧睾丸有一个3×2厘米的低回声区，提示原发性睾丸肿瘤，很可能是精原细胞瘤。切除睾丸的组织学评估显示为纤维组织，但未发现明确的肿瘤。
