[Pseudosarcoma of the bladder. Apropos of a case of inflammatory tumor of the bladder].

The authors report a case of benign pseudosarcoma of the bladder and emphasize the endoscopic features of the tumour, which were highly suggestive of malignancy, leading to the decision to perform cystectomy. The diagnosis was corrected by endoscopic resection and histology. Treatment usually consists of partial cystectomy, but can sometimes be limited to one or several endoscopic resections.
