AGA Institute GastroSlides Unit on Inflammatory Bowel Disease Pathology



This teaching unit represents a set of selected images that illustrate important aspects of the pathology associated with inflammatory diseases of the intestines. Although focused on idiopathic ulcerative colitis and Crohn’s Disease, the unit also reviews aspects of other inflammatory intestinal conditions, including microscopic colitis and C. difficile colitis. The outstanding detailed and labeled microscopic sections accompanied by explanatory legends that contain recent literature citations provide a unique teaching and self-education resource that can be used alone or may complement other GTP units (e.g. Inflammatory Bowel Diseases, 3rd edition). The author, Paul E. Swanson, MD, is professor of pathology and director of anatomic pathology, at the University of Washington Medical Center, Seattle.

The author acknowledges the important contributions of three individuals:

Dr. Basil Morson, whose reasoned approach to pathologic diagnosis enlightened me to the
possibilities of gastrointestinal pathology and on whose body of published work much of this unit depends.

Dr. Mary Bronner, my colleague at the University of Washington, who has taught me more in two years about practical elements of colon biopsy interpretation than I was able to glean from 11 years of practice in the field, and who graciously allowed me the use of photographic material used in the preparation of slides.

Dr. David Alpers, dear friend and colleague, whose remarkable knowledge of both clinical gastroenterology and gastrointestinal pathology guided the form and concept of this unit, and whose infinite patience allowed me the undeserved opportunity to offer these images and ideas to the members of the American Gastroenterological Association.
