[Synchronously diagnosed and treated triple cancer (rectum-ureter-prostate)]

A 63-year-old man was admitted for examination of a rectal tumor. A stony hard nodule was palpated in his swollen prostate by rectal examination. The biopsies proved rectal and prostate carcinoma. Transabdominal echogram and DIP showed left hydronephrosis. Left ureteral cancer was suggested by the typical "goblet sign" with retrograde ureterography. Rectal lower anterior resection, left total nephroureterectomy with partial cystectomy, castration and pelvic lymphadenectomy were undertaken synchronously. The pathohistological diagnosis was triple cancer consisting of rectal mucotubular adenocarcinoma, prostatic carcinoma and ureteral transitional cell carcinoma. The diagnosis and treatment of the triple cancer were discussed.
