We present a case of a 67-year-old patient with a history of augmentation ileocystoplasty 31 years ago following genitourinary tuberculosis. 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 year 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.
我们报告一例67岁患者，31年前因泌尿生殖系统结核接受了回肠膀胱扩大术。因无症状性镜下血尿进行的影像学检查发现新膀胱内有3个强化息肉。患者接受了肠膀胱前列腺切除术，新膀胱的组织病理学检查显示所有3个息肉均为黏液腺癌，同时伴有 Gleason 7（3+4）级前列腺腺癌。辅助化疗及1年随访后，他无临床或影像学复发迹象。考虑到这一罕见病例，我们讨论了尿路重建中纳入肠段后恶性肿瘤的发生情况，展示了继发性肿瘤生长、原发性疾病与所采用的尿流改道类型之间存在何种关系。
