Germ cell tumors are the most common type of testicular cancer. The most typical symptom of testicular cancer is a painless lesion in the testis. Less frequent symptoms include gynecomastia and testicular pain. Males between the ages of 15 and 35 are most frequently affected by testicular malignancies, which make up 1% of all cancer cases in men. Seminomas and nonseminomas are the two types of testicular germ cell cancers. More than half of diagnoses for germ cell cancers are seminoma.^1-4

Although only a small percentage of seminoma patients have distant metastases at diagnosis, Lung, bone, liver, and retroperitoneal lymph nodes are among the organs where seminomas frequently metastasize.^{1, 5, 6} The majority of kidney malignancies are primary neoplasms. Secondary kidney tumors are relatively uncommon in clinical practice. ^{7, 8}

In this study, we report the clinic-pathological, radiological, and immunohistochemical findings of a case of seminoma metastasis to the kidney and cervical lymph node after 25 years of interval.
