Evaluation and reporting of biopsies from the columnar-lined esophagus and gastro-esophageal junction (GEJ).

This review is part of a collaboration between the American Registry of Pathology (the publisher of the Armed Forces Institute of Pathology Fascicles) and Annals of Diagnostic Pathology. It is in a series of expert recommendations on topics encountered in daily practice. The authors, two pathologists and a gastroenterologist, met on 19 January 2019 tasked with developing expert recommendations on reporting biopsies from the columnar lined esophagus and gastroesophageal junction. Our opinions for reporting revolve around noting the presence and absence of goblet cells and clues for confirming whether a sample is from the tubular esophagus. We also illustrate congeners of goblet cell. We present the information in the form of questions and answers.
