[Three cases of unusual non-germ cell tumors of the testicle].

By describing 3 clinical cases of unusual testicular non germinal tumors, including an adenoma of the rete testis, an undifferenciated sex cord tumor and a mesothelioma of the tunica vaginalis, we make a literature review of the unusual testicular tumors and testicular apendix, including their incidence and management. Also and as one of our conclusions, we expose the importance of the intraoperatory biopsy in the testicular cancer surgery, because even if it is infrecuent, the presence of this rare testicular tumors, in which if they are proven to be benign, the testicular unit could be preserved and the radical orquiectomy could be avoided.
