Peritoneal carcinomatosis and hepatic infiltration related to the dissemination of a micropapillary cell carcinoma of the bladder

Most cases of liver failure related to the infiltration of the liver by neoplastic cells are associated with hematological neoplasia or small cell carcinoma of the lung. We report case of liver failure related to a rare infiltration of the liver by a micropapillary bladder carcinoma. Micropapillary bladder cell carcinomas have recently been isolated among bladder tumors. They are characterized by life-threatening features as they spread rapidly to the interstitial stromal matrix leading to a highly aggressive course. The present case emphasizes the pathological features and poor prognosis of these neoplasia, as rapid submucosal spreading may prevent curative locoregional treatment.
