We report 9 clinicopathological cases of inverted papilloma. The occurrence of associated true malignant epithelial tumors in the urinary tract in 4 patients is not concurrent with previous reports. Even though inverted papilloma per se is a benign lesion it may be associated with malignant epithelial tumors of the urinary tract. The similarity between proliferative lesions of the bladder and inverted papilloma is discussed. The possibility of common etiologic factors of proliferative cystitis, cystitis cystica, cystitis glandularis, inverted papilloma and ordinary bladder tumors may be considered.
我们报告了9例倒置性乳头状瘤的临床病理病例。4例患者尿路中出现相关的真性恶性上皮肿瘤，这与先前的报道不一致。尽管倒置性乳头状瘤本身是一种良性病变，但它可能与尿路恶性上皮肿瘤有关。本文讨论了膀胱增生性病变与倒置性乳头状瘤之间的相似性。增生性膀胱炎、囊性膀胱炎、腺性膀胱炎、倒置性乳头状瘤和普通膀胱肿瘤可能存在共同病因的可能性也值得考虑。
