[Papillo-polypoid cystitis. Focal cystitis with pseudoneoplastic aspect].
Report on 12 patients with vesical papillary changes of the mucosa, endoscopically assessed as tumours, but where the pathological study showed to be no epithelial neoplastic changes, since exophitical growth was a consequence of the submucosal edema (91.6%) with a moderate inflammatory reaction. Twenty-five percent cases exhibited no causative factors and 75% were correlated to urethral catheter (average 2.3 months). Due to major the and microscopic similitude between low degree transitional cell carcinoma and the localized inflammatory changes (papillary cystitis) the criteria to establish a correct diagnosis are discussed.
