Abstract

Sir, We thank Professor Donnez for his interest and considered response in regard to our article (Colgrave et al., 2020). In current practice, a pathologist will diagnose endometriosis using sections from biopsies stained with haematoxylin and eosin. The primary aim of Colgrave et al. (2020) was to determine whether menstrual cycle-related and other clinically useful histological lesion features could be identified using these routine pathology processes without introducing additional immunohistochemical protocols. For this reason, we did not include immunohistochemical studies in this project. However, we agree with Professor Donnez that ongoing research examining lesion characteristics including steroid receptors and specific immune cell makers using samples available to us from our extensive and well-annotated tissue bank would be invaluable and is planned. Also, progesterone resistance may well contribute to the heterogeneity we observed, and it will be fascinating to determine whether steroid receptor expression relates to glandular (as...
