Testicular Metastasis From Adenocarcinoma Of The Prostate. The Internet Journal of Surgery. 2006 Volume 9 Number 1. Abstract Secondary testicular tumors are very rare. Metastatic deposits in the testes from prostatic adenocarcinoma, although rare, have been reported. Other common primary sites include lungs, kidneys, colon, and stomach. We report a case of testicular metastasis from adenocarcinoma of the prostate. INTRODUCTION Metastatic spread to the testis from prostatic adenocarcinoma is rare. Usually cancer of the prostate spreads to the regional lymph nodes, bones, liver and lung. 1 The English literature reveals only 76 cases of adenocarcinoma of the prostate metastasising to the testis until 2000, eventually there have been isolated case reports. 2 , 3 CASE REPORT An 82 year old man of Indian origin was admitted in the hospital with complaints of urinary retention, swelling in the right inguinal region and slight enlargement of the right testis. On ultrasound and CT scan, diagnosis of carcinoma of the prostate was suggested. Serum P.S.A levels were 49.5 ng/ml (normal 4 ng/ml). Needle biopsy of prostate on histopathological examination revealed adenocarcinoma of the prostate. Subsequently, therapeutic bilateral orchiectomy was done. PATHOLOGICAL FINDINGS On gross examination the right testis measured 5 x 3.5cm and was externally nodular. Cut section showed multiple tiny gray white areas scattered diffusely in the testicular parenchyma (Fig.1). Figure 1 Figure 1: Gross photograph showing nodular external surface of the testis. Left testis measured 4 x 2.5 cm and was unremarkable externally as well as on cut section. On histological examination, the right testis showed atrophy of the testicular parenchyma and presence of areas of well to moderately differentiated adenocarcinoma in the interstitium (Fig.2 & 3). Histological examination of left testis showed atrophied parenchyma but no metastatic tumor deposits were identified.
