Abstract

We report a rare case of testicular metastasis from prostate cancer. A 68-year-old patient presented with a right testicular mass with discomfort. He had a history of robot-assisted laparoscopic radical prostatectomy and had received adjuvant radiation therapy and had been treated with androgen deprivation therapy continuously at another institution. We performed a right inguinal orchiectomy. The testicular mass was diagnosed as a metastasis from prostate carcinoma.

Figure

• 

  FIG. 1 Ultrasonography showing an ovoid, hyperechoic and heterogeneous 2.4×1.7×2.0 cm sized intratesticular mass in the right testis.

• 

  FIG. 2 Gross photograph showing a 2.5×2.5×2.5 cm well-defined white mass pushing the adjacent normal testis tissue.

• 

  FIG. 3 The tumor consists of characterized tall columnar cells, which form a single or pseudostratified layer. At low magnification, infiltrating cribriform and papillary growth patterns are present (H&E, ×40).
