両側精巣固定術後に両側精巣腫瘍を同時に発症した1例

Abstract

We report a case of bilateral testicular tumor after bilateral orchiopexy. A 42-year-old man who underwent bilateral orchiopexy in early childhood consulted our hospital due to right testicular enlargement in February 2012. Blood tests revealed elevation of human chorionic gonadotropin β, and a right testicular tumor was suspected. No metastasis was found on contrast-enhanced computed tomography. Although there was no swelling in the left testis, a heterogeneous hypoechoic mass was detected on left scrotal ultrasonography, and bilateral testicular tumors were supected. Left testis biopsy was performed and an intraoperative rapid diagnosis of a testicular tumor was made. Bilateral high orchiectomy was performed. No recurrence has been found over follow-up for 36 months after surgery.
