Review Case Reports
[A case of metachronous testicular tumor developing seven years after complete remission of retroperitoneal extragonadal germ cell tumor].
A 26-year-old man was admitted to our hospital with a chief complaint of left cervical lymphadenopathy. He was diagnosed as having seminoma by needle biopsy. Computed tomography revealed an aorto-caval retroperitoneal tumor. ⋯ Neither distant metastasis nor lymph node metastasis was detected by computed tomography. Right radical orchiectomy was performed and histology revealed seminoma with yolk sac tumor components. No recurrence has been seen after 10 months.
