A case of prostatic metastasis from non‐seminomatous testicular cancer

Abstract

IntroductionProstatic metastasis from testicular cancer is extremely rare, with only 10 reported cases, all of which were diagnosed as relapse. Herein, we report the case of a patient with concurrent testicular cancer and prostatic metastasis.Case presentationA 57‐year‐old man presented at our emergency department with urinary retention. A painless mass was found in the right scrotum, and computed tomography showed lung, mediastinal, and liver metastases, and an enlarged prostate. Tumor markers were measured in 2057 U/L lactate dehydrogenase, 2460 mIU/mL human chorionic gonadotrophin, 1303 ng/mL alpha‐fetoprotein, and 1.51 ng/mL prostate specific antigen. An orchiectomy and biopsy were performed; the pathological results showed immature teratomas, embryonal carcinomas, choriocarcinomas, and seminomas in the testis, and embryonal carcinomas in the prostate, liver, and mediastinum. The patient refused chemotherapy and died 3 months following diagnosis.ConclusionProstatic metastasis should be considered in cases of dysuria or prostate enlargement in testicular cancers.

Robot‐Assisted Laparoscopic Radical Prostatectomy for Prostatic Metastatic Recurrence from Testicular Cancer

“…One case of testicular cancer with prostate metastasis at initial presentation has been reported [ 16 ]. However, prostate metastatic recurrence in patients with stage 1 testicular tumors treated with adjuvant chemotherapy following radical orchiectomy has not been reported.…”
