In the uninvolved kidney parenchyma of three cases with Wilms' tumor neoplastic metanephric aberrations were found which represent regressive forms of the nodular renal blastema-nephroblastomatosis complex. Their histopathologic features are demonstrated. They are designated as simple or diffuse metanephric epithelial hamartomas. Small lesions show involution resulting in scars. In the central parts of larger lesions cysts and adenomas were detected. The latter were multicentric and revealed compact-epithelial, papillary-psammomatous, cystic-multilocular and tubulo-papillary forms. Their origin, possible evolution, relationship to nephroblastoma as well as their significance are discussed.
在3例肾母细胞瘤患者未受累的肾实质中发现了肿瘤性后肾异常，这些异常代表了结节性肾胚基-肾母细胞瘤病复合体的退行性形式。展示了它们的组织病理学特征。它们被命名为单纯性或弥漫性后肾上皮错构瘤。小病变显示退化形成瘢痕。在较大病变的中央部分检测到囊肿和腺瘤。后者为多中心性，呈现致密上皮、乳头-砂粒体、囊性多房和小管-乳头形式。讨论了它们的起源、可能的演变、与肾母细胞瘤的关系及其意义。
