Non-neoplastic gastrointestinal diseases constitute a major component of the workload for the general surgical pathologist. Many new and variant forms of inflammatory bowel disease have been described in recent years; several of these enter the differential diagnosis of chronic idiopathic inflammatory bowel disease (Crohn’s disease and ulcerative colitis). The primary objectives of this course are to present an update and review of the “atypical” colitides (including collagenous colitis, lymphocytic colitis, and diversion colitis), prolapse injury, drug-related and iatrogenic enterocolitides, ischemic enterocolitis, and selected infectious enterocolitides. New patterns and controversies in ulcerative colitis and Crohn’s disease will also be covered. The discussion will include histologic criteria as well as clinicopathologic and endoscopic correlates, new diagnostic techniques, and reporting issues.

This course is intended primarily for practicing general surgical pathologists and residents in training with an interest in non-neoplastic disorders of the intestines. There are no materials for advance mailing, but all registrants will be mailed a CD of relevant course material after the meeting. A syllabus will be distributed at the course.
