A 30 year-old man was admitted to our hospital with a chief complaint of left flank pain. Computed tomography revealed a retroperitoneal tumor. Levels of lactic dehydrogenase, human beta-chorionic gonadotropin, alpha-fetoprotein, DUPAN-2 and carbohydrate antigen 19-9 were elevated. No abnormal findings were present according to palpation and ultrasonography of the testes. The patient was diagnosed as having a retroperitoneal extragonadal germ cell tumor (EGCT) considering the elevated markers. Resection of the tumor, two cycles of neoadjuvant and one cycle of adjuvant chemotherapy (cisplatin and etoposide) were performed. The surgical specimen showed total necrotic tissue. Eight years later, the patient noticed an enlargement of his left testicle. The tumor felt elastic and firm on his left testis. Neither distant metastasis nor lymph node metastasis was present according to computed tomography. Left high orchiectomy was performed and histology revealed seminoma. Twenty-three cases have been reported previously about metachronous testicular tumor developing after retroperitoneal EGCT. We report the 24th case.

Our patient was a 31-year-old man who presented with right flank pain. Computed tomography revealed multiple tumors in the liver and lungs, with marked elevation of serum human chorionic gonadotropin (HCG) and alpha-fetoprotein (AFP) levels. In addition, no testicular abnormalities were detected by palpation or ultrasonography. On the bases of these results, the patient was diagnosed with extragonadal germ cell tumor and was therefore started on chemotherapy with bleomycin, etoposide, and cisplatin (BEP). However, the result of a subsequent blood test showed marked pancytopenia at the initial stage of treatment. We speculated that the cause of anemia was not only bone marrow suppression but also intratumoral hemorrhage, collectively termed choriocarcinoma syndrome. After conservative treatment involving blood transfusion and administration of granulocyte colony-stimulating factor, he recovered. After several chemotherapy sessions, the levels of all tumor markers returned to normal. Finally, the patient underwent hepatectomy for residual tumors ; but, the resected specimen showed no viable cancer cells. Currently, the patient is free from disease since the last chemotherapy session, administered 5 months ago.
