Kupffer hyperplasia and hypertrophy may also occur in inflammatory conditions. The enlarged Kupffer cells may form sheets or small nodules. ## 英文原文 · Recommendation This tissue change is rare in untreated rodents and should be diagnosed and graded whenever present. A description of the morphologic features and tissue distribution should be detailed in the pathology narrative. Because hypertrophy is a consequence of the phagocytic activity of these cells, a separate diagnosis of hypertrophy is generally not necessary. If pigmentation is prominent, a separate diagnosis of pigmentation, along with a qualitative grading of severity, may be appropriate. ## 配图 - https://www.labsmart.cn/ntp-atlas-images/ntp_0371.jpg 整理:北京天融慧通科技有限责任公司(LabSmart)| https://www.labsmart.cn
