Prostatic carcinoma is one of the most common malignancy in aged males. The incidence of metastatic prostatic adenocarcinoma is well known with most common site being the bone followed by lung and liver. Metastasis to testis is rare and very few cases have been reported till date. We present a case report of 80 year old male who presented with swelling in the left testis since last 4 months with a history of radical prostatectomy performed 3 year back for resection of a malignant growth in the prostate. Left inguinal orchiectomy was done. Histopathological examination showed foci of atypical cells in acinar arrangement infiltrating into the tunica adventitia of the testis, suggestive of metastatic prostatic adenocarcinoma to the testis. Positive immunoexpression of AMACR and negative p63 expression further potentiated our diagnosis. This case report stresses the need for aggressive post-operative follow up in prostatic carcinoma patient and to consider the need of prophylactic orchiectomy in old patients.
