Abstract

BackgroundYolk sac tumor endodermal sinus tumor is a rare malignant germ cell tumor arising in the testis or ovary. Extragonadal yolk sac tumor is even rarer and has only been described in case reports. Due to the rarity of the tumors, the appropriately optimal treatment remains unclear. We report a case of yolk sac tumor in the seminal vesicle.

CaseA 38-year-old Asian male presented with gross hematuria and hemospermia. Transrectal ultrasound scan showed a solid mass in the left seminal vesicle and the scrotal sonography showed no abnormalities. Bilateral seminal vesicles were resected, and histopathological examination showed a typical pattern of yolk sac tumor YST. The patient responded poorly to comprehensive treatment of radiotherapy, chemotherapy and surgeries, developed systemic multiple metastases, and died of cachexia one and half years after diagnosis.
