Abstract

Metastases from bladder transitional cell carcinoma (TCC) to the testis are very rare. These are usually found on autopsy and occur in advanced or metastatic bladder cancers. More common, known primary tumors that metastasize to the testis include prostate, lungs, melanoma, gastro-intestinal tract and the kidney. We report a rare case of solitary and synchronous metastatic TCC of the bladder to the testis, discovered on histological examination. This case illustrates that metastatic neoplasm to uncommon sites should be considered in the differential diagnosis for patients with a history of advanced bladder TCC.
