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.
关于12例膀胱黏膜乳头状改变患者的报告，内镜检查评估为肿瘤，但病理研究显示无上皮性肿瘤改变，因为外生性生长是黏膜下水肿（91.6%）伴中度炎症反应的结果。25%的病例未发现致病因素，75%与尿道导管有关（平均2.3个月）。由于低度移行细胞癌与局限性炎症改变（乳头状膀胱炎）在大体和显微镜下有很大相似性，因此讨论了建立正确诊断的标准。
