A case of recto-sigmoid adenocarcinoma, developing 25 years after bilateral uretero-sigmo dostomy for extrophia vesicae in a 29 year old man. A study of the literature emphasises the long delay before its appearance, the gastrointestinal nature of the tumour and its grave prognosis. The pathogenesis of this lesion is unknown at present, and consideration should be given to the effects of urine on the digestive mucosa and the role of a possible inflammatory granuloma, but also the possibility of a urinary tract origin, despite the apparent histological contradiction. |
