Implantation metastasis of prostate cancer in a suprapubic cystostomy tube needle tract.

A 64-year-old male patient with a serum PSA value of 51.91 ng ml(-1) and an magnetic resonance imaging scan suggestive of prostate cancer was admitted with bilateral hydronephrosis and anemia. A suprapubic cystostomy had been inserted 6 months earlier, owing to voiding difficulties. The patient was found to have huge multiple bladder stones and a massively thickened bladder wall. A sectio alta with bladder stone removal and bilateral ureteral stenting was performed. Histopathological examination revealed the growth of prostate cancer cells in the cystostomy tube needle tract.
