膀胱内生性乳头状瘤是一个主要见于成年男性,呈良性经过,但病理和临床都极易误诊为膀胱移行细胞乳头状癌的独立性病变。因此日宜引起国内、外重视。 1963年potts报告一例,第一次正式称为膀胱内生性乳头状瘤。并详细描述了它的形态特征。但其后的十多年中文献上仅有数例报导。1975年Henderson报告5例并复习文献,认为镜下形态和鼻腔、副鼻窦的内生性乳头状瘤非常相似,并对肿瘤的蒂部和基底部作了详细的形态学观察,没有发现有浸润。同年,DeMeeter从复习1942——1974年间美国纪念医院有关膀胱的资料中报告20例,其中17例病理均误诊,误诊的病名有:腺性膀胱炎,囊性膀胱炎,布隆氏上皮巢,布隆氏上皮巢
