Radiological investigations performed due to asymptomatic microscopic haematuria revealed three contrast-enhancing polyps within the neobladder. The patient had enterocystoprostatectomy and histopathological examination of the neobladder revealed mucinous adenocarcinoma in all three polyps, together with a prostatic adenocarcinoma Gleason 7 (3+4). After adjuvant chemotherapy and 1\u2005year of follow-up, he had no sign of clinical or radiological recurrence. Taking into consideration this rare case, we discuss the development of malignant tumours after the incorporation of intestinal segments in a urinary tract reconstruction, showing what relationship exists between secondary neoplastic growth, the primary disease and the type of urinary diversion utilised.<\/jats:p>","DOI":"10.1136\/bcr-2013-009499","type":"journal-article","created":{"date-parts":[[2013,8,1]],"date-time":"2013-08-01T06:15:20Z","timestamp":1375337720000},"page":"bcr2013009499","source":"Crossref","is-referenced-by-count":4,"title":["Intestinal
