Even though prostate carcinomas are the ones which more frequently metastasize the testis, this has only happen in 0.12% of our series, representing 0.9% of testicular tumours in our centre. Revision of such an uncommon pathology shows that in most instances they are asymptomatic, and that the likely route for dissemination is lymphatic, therefore they are not necessarily associated to visceral metastasis, while their repercussion in the prognosis is limited.
