Core Tip
Core tip: Although the concept of immunoglobulin G4 (IgG4)-related gastrointestinal disease remains unclear, there appear to be two types of IgG4-related gastrointestinal disease. One is a gastrointestinal lesion showing marked thickening of the wall of the esophagus and stomach, consisting of dense fibrosis with abundant infiltration of IgG4-positive plasma cells, which usually show submucosal spreading. The other is an IgG4-related pseudotumor occurring in gastrointestinal regions such as the stomach, colon, and major duodenal papilla, showing polypoid or mass-like lesions. It is of utmost importance to rule out malignancy. To avoid unnecessary resection, IgG4-related gastrointestinal diseases should be considered in the differential diagnosis.
