Extragonadal germ cell tumor of the prostate associated with Klinefelter's syndrome
1Department of Urology, Tokyo Medical University, Japan. k-namiki@tokyo-med.ac.jp
Purpose:
We report on a case of extragonadal germ cell tumor of the prostate associated with Klinefelter's syndrome.
Methods/Results:
The patient was a 33-year-old man. A transrectal prostate biopsy suggested combined germ cell tumor (yolk sac tumor + teratoma). Because there was no tumor except from the prostate, we considered this case to be a primary extragonadal germ cell tumor of the prostate. The prostate tumor responded to systemic chemotherapy with cisplatin, vinblastine and bleomycin and elevated lactate dehydrogenase and alpha-fetoprotein levels normalized. In addition to chemotherapy, the patient also underwent radiation therapy.
Conclusion:
The patient has survived for approximately 4 years since the diagnosis.
