A case of bladder cancer with direct rectal invasion

Abstract

A 68-year-old man came to our hospital because he got edema in his left leg. Abdominal CT scan revealed multiple liver metastasis and pelvic CT scan showed marked thickening of the rectal wall and the border with the bladder became indistinct. Colonoscopic examination revealed stenosis of the rectum without mucosal abnormality. Histological examination of boring biopsies from this lesion led to the suspicion adenocarcinoma. His condition turned worse and died 1 month later. From the autopsy findings we diagnosed advanced bladder cancer with direct rectal invasion. Because this metastasis form is very rare, we report on this case along with a review of the literature.
