Based on cumulative experience from subspecialty-based GI practices, this faculty ensemble has identified pathologic entities and concepts in GI, liver and pancreatic pathology that continue to pose diagnostic challenges on a daily basis. Such challenges relate directly to interpreting limited biopsy samples, generating succinct differential diagnoses (particularly for inflammatory conditions, medical liver injury, non-adenocarcinoma neoplasia of pancreas, and non-GIST mesenchymal tumors), the impact of genetics on diagnosis and classification, constantly changing disease classifications and the fluidity of practice guidelines in the context of emerging evidence-based data.
Target Audience Practicing academic and community pathologists, and pathologists-in-training
Learning Objectives Upon completion of this educational activity, learners will be able to:
- Review the spectrum of inflammatory disorders affecting upper and lower GI tract and discuss diagnostic pearls for accurate classification
- Assist participants in recognizing histologic features used to grade Barrett and IBD-related dysplasia, differentiate dysplasia from reactive atypia and understand current guidelines for managing dysplasia in these settings
- Provide a practical diagnostic approach to colorectal polyps, polyposis syndrome, appendiceal neoplasms and mesenchymal tumors of the gastrointestinal tract
- Discuss a pattern-based approach to liver injury with the help of ancillary stains and learn to classify liver neoplasms on limited samples
- Learn the algorithmic approach to diagnose non-neoplastic and neoplastic pancreaticobiliary disorders and their mimics, especially in small biopsies
