The nephrogenic adenoma is a peculiar lesion of the urinary bladder characterized partly by villous and partly by gland-like structures. The two layered surface epithelium consists of an eosinophilic cell layer, which covers a clear cell layer, the latter resting upon a delicate basal layer. The clear cells disappear when approaching the tip of the villi. There exists a 200 micron wide zone of transition between the urinary bladder epithelium and that of the neprogenic adenoma. At the base of the villi there are scattered nodules of gland-like structures lined either by eosinophilic cells or by clear cells. These epithelial cells are derived from the corresponding surface epithelial cells from which they had separated by active downwards growth.
肾源性腺瘤是膀胱的一种特殊病变，部分特征为绒毛状结构，部分为腺样结构。两层表面上皮由嗜酸性细胞层组成，其覆盖着透明细胞层，后者位于一层薄的基底层之上。当接近绒毛顶端时，透明细胞消失。膀胱上皮与肾源性腺瘤上皮之间存在一个200微米宽的过渡带。在绒毛底部有散在的腺样结构结节，由嗜酸性细胞或透明细胞衬里。这些上皮细胞源自相应的表面上皮细胞，它们通过活跃的向下生长而与之分离。
