The authors report a case of benign pseudosarcoma of the bladder and e
mphasize the endoscopic features of the tumour, which were highly sugg
estive of malignancy, leading to the decision to perform cystectomy. T
he diagnosis was corrected by endoscopic resection and histology. Trea
tment usually consists of partial cystectomy, but can sometimes be lim
ited to one or several endoscopic resections.
