Testicular metastasis as the first manifestation of colon carcinoma

J Urol. 1988 Sep;140(3):621-2. doi: 10.1016/s0022-5347(17)41740-x.


Metastatic carcinoma to the testes is uncommon, and it is most often found incidentally at autopsy or after orchiectomy for prostatic carcinoma. One of the rarest causes of testicular tumor is metastasis from another primary site. It is even more unusual when the metastasis to the testicle is the first manifestation of the tumor. We report a case of asymptomatic colon carcinoma presenting as metastases to the testis and epididymis, which was diagnosed after biopsy of testicular nodules. Although nonlymphomatous cancer presenting as an intrascrotal mass is extremely rare, seldom detected clinically and almost never the first sign of disease, it should be considered a possibility, even in the young adult who presents with a mass involving the testicle or epididymis.
