Abstract

IgG4-related disease (IgG4-RD) is an immune-mediated fibroinflammatory disease that responds to glucocorticoids, which is gradually well known in recent years. It can involve multiple organs of patients, including pancreas, bile duct, gallbladder, salivary gland, orbital tissue, lung, liver, lacrimal gland, kidney, retroperitoneal, aorta, thyroid and lymph node, [1] in which gastrointestinal involvement is relatively rare [2]. Most of the known reports of isolated gastric IgG4-related lesions were accidental found (in physical examination or other site examination), and often treated as Gastrointestinal Stromal Tumors (GIST) lead to surgically resection. In addition, Calcified Fibrous Tumor (CFT) in gastrointestinal tract often occurs with submucosa [3] is histologically similar to IgG4-RD, [4] whether it belongs to IgG4-RD is still controversial. Therefore, the diagnosis of IgG4-RD especially in GI tract remains difficult and important. Here, we reported a case of isolated IgG4-related gastric lesion which was diagnosed as GIST and treated by surgical resection.
