Seminoma with elevated human chorionic gonadotropin. The case for retroperitoneal lymph node dissection.
An elevated serum level of human chorionic gonadotropin (HCG) in a patient whose primary tumor histologically appears to be a pure seminoma implies the presence of syncytiotrophoblastic giant cells either detectable by careful step sectioning of the primary tumor or present in metastatic disease. Inasmuch as the malignant potential and radioresponsiveness of syncytiotrophoblastic giant cells are unknown and the serum elevation of HCG may signal metastatic embryonal carcinoma, retroperitoneal lymph node dissection with adjuvant chemotherapy dependent on pathologic staging should be considered for patients with seminoma and postorchiectomy elevated HCG levels. An illustrative case is herein reported.
