Nodular regenerative hyperplasia of the liver is characterized grossly by diffusely nodular liver resembling micronodular cirrhosis. Viewed microscopically, the nodules consist of regenerative parenchyma without fibrosis, which are usually smaller than the hepatic lobule. Nodular regenerative hyperplasia is distinct from other nodular lesions of the liver such as cirrhosis, partial nodular transformation, focal nodular hyperplasia, and adenoma. Although nodular regenerative hyperplasia is seldom reported, it may occur more frequently than it is recognized.
肝脏结节性再生性增生的大体特征是肝脏弥漫性结节状，类似小结节性肝硬化。显微镜下观察，结节由无纤维化的再生实质组成，通常小于肝小叶。结节性再生性增生与肝脏的其他结节性病变如肝硬化、部分结节性转化、局灶性结节性增生和腺瘤不同。虽然结节性再生性增生很少被报道，但它的实际发生率可能比目前认知的更高。
