Classic renal metastatic seminoma
نویسندگان
چکیده
introduction: Seminoma comprises ~50% of testicular germ cell tumors. Renal metastases are infrequent and are usually diagnosed at necropsy. Clinical case: A 24-year-old male with a history of left radical orchiectomy and adjuvant radiotherapy due to classic seminoma (stage I) showed elevated levels of b-human chorionic gonadotropin and lactate dehydrogenase during the 11-month follow-up. Computed tomography showed a 9 × 8 cm lobulated, heterogeneous tumor in the left kidney. Histopathological and immunohistochemical assay demonstrated a classical metastatic seminoma. Conclusions: The majority of renal tumors represent a primary neoplasm; in patients with extra-renal tumors we must consider the possibility of metastatic disease.

To develop a more appropriate therapeutic strategy for treatment of nonpulmonary visceral metastatic testicular seminoma based on the International Germ Cell Consensus Classification, we reviewed the medical records of patients with nonpulmonary visceral metastatic testicular seminoma who were treated over a 20-year period. Only 15 (2.2%) of the 686 cases of testicular seminoma were nonpulmonar...
