An Oasis of Gastrointestinal Pathology 2020

Diagnostic gastrointestinal pathology is experiencing dynamic, fluid changes that require the attention of surgical pathologists who specialize in this area or who sign-out biopsies from the GI tract and liver. There are updates in the AJCC staging of mucinous neoplasms of the appendix and conceptual changes in interpreting appendectomy samples containing luminal and extra-appendiceal mucin; there is confusion about the diagnosis and outcome of so-called goblet cell carcinoid, and a new classification scheme is available; Barrett’s esophagus is often over-diagnosed but a new method informs separation of reactive changes from low-grade and indefinite dysplasia; spindle cell tumors can be separated morphologically and by their molecular features; overlapping patterns of injury are encountered in disease and iatrogenic conditions, but can be separated; liver pathology has become more challenging in the context of treatment for Hepatitis C; certain infections maybe mistaken for inflammatory disease, requiring criteria for identification and diagnosis. This faculty derived from the Rodger C. Haggitt Gastrointestinal Pathology Society (GIPS) is poised to provide the latest information in these challenging areas in a unique mentoring environment.
