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.
免疫球蛋白G4相关性疾病(IgG4-RD)是一种全身性炎症性疾病,其特征是IgG4阳性浆细胞浸润和全身各器官纤维化。IgG4-RD累及胃肠道(IgG4相关性胃肠道疾病;IgG4-GID)较为罕见,疾病概念仍不明确。一般来说,IgG4-GID有形态学改变的报道,包括溃疡、狭窄和黏膜下肿瘤。在此,我们报告一例伴有持续性腹泻和腹痛的IgG4-GID病例,该病例无典型的内镜检查结果。该病例提示了IgG4-GID存在尚未明确的临床特征。
