Solitary parenchymal metastases of renal cell carcinoma to the penis or testis are rare. We report 1 case of each: in one instance the patient presented with priapism and an asymptomatic primary tumor; in the other, the metastasis presented as an acute change in a long-standing hydrocele more than one year after nephrectomy. Both patients had either positive margins at resection or recurrence after resection of the metastasis. While long-term, disease-free survival has been reported after orchiectomy for isolated metastatic disease, penile involvement appears to carry a very poor prognosis.
肾细胞癌孤立性实质转移至阴茎或睾丸罕见。我们各报告1例：1例患者表现为阴茎异常勃起及无症状原发性肿瘤；另1例患者在肾切除术后1年多，转移灶表现为长期存在的鞘膜积液急性变化。2例患者转移灶切除时切缘均阳性或切除后复发。虽然对于孤立性转移病灶行睾丸切除术后有长期无病生存的报道，但阴茎受累似乎预后很差。
