%X Immunoglobulin G4-related disease (IgG4-RD) is a systemic inflammatory disease characterized by the infiltration of IgG4-positive plasma cells and fibrosis in organs throughout the body. IgG4-RD involvement in the gastrointestinal (GI) tract (IgG4-related GI disease; IgG4-GID) is rare, and the disease concept remains unclear. Generally, IgG4-GID has been reported with morphological changes, including ulcers, strictures, and submucosal tumors. Here, we report a case of IgG4-GID with persistent diarrhea and abdominal pain in which typical endoscopic findings were absent. This case suggests the unidentified clinical features of IgG4-GID.
