- 请教“epithelial displacement” 和 “anastamosing”
1、One of the challenges associated with core biopsy, particularly with reference to papillary lesions, is the phenomenon of "epithelial displacement".
2、Microscopically, pseudoangiomatous stromal hyperplasia(PASH) is composed of anastamosing slit-like spaces in a densely collagenized stroma.
请教老师，epithelial displacement和anastamosing应该怎么解释呢，谢谢老师！这是乳腺病理中的内容。

刚开始看英文书的时候，最好是中英文对照看，不一定是同一本书的翻译版
同意一了的意见，就是”epithelial displacement“没有上下文，不知道是什么，你看的哪本书？
谢谢老师。这本书是Illustrated Surgecal Pathology---------Breast.作者是Thomas J. Lawton。
上下文是讲management of papillary lesions(乳腺乳头状病变的处理)。
One of the challenges associated with core biopsy, particularly with reference to papillary lesions, is the phenomenon of "epithelial displacement". Due to the unique nature of papillary lesions, often small clusters of cells that appear to be infiltrative can be identified in the biopsy tract following core needle biopsy. It is critical to place these cells in perspective and not to overdiagnose invasive carcinoma. The benign appearance of the cell clusters (which often have a squamoid appearance) as well as their presence within the loose fibrosis, fat necrosis, and hemorrhage associated with a prior biopsy site can aid in this distinction.
High-power view of the benigh-type clusters of cells within a biopsy tract characteristic of epithelial displacement. These cell clusters should not be confused with invasive carcinoma.
