[Testicular metastasis of transitional cell carcinoma of the prostate].

This case illustrates in a 55 year old man a testicular metastasis from a prostatic TCC occurring fourteen years after a bladder localisation of the same type. To our knowledge no other similar observation has been reported in the literature so far. Metastatic disease should be considered in the differential diagnosis of testis tumours arising in patients with a history of urothelial TCC from bladder, ureter or even prostate as described here.
