| Abstract |
|
Immunoglobulin G4-related disease (IgG4-RD) is a fibroinflammatory condition characterized by the tendency to form tumefactive lesions. However, the disease has highly variable clinical manifestations, as IgG4-RD can affect any organ. The biliary tree and major salivary glands are commonly affected; however, bowel mucosa is rarely affected. A 41-year-old man presented to our hospital complaining of abdominal pain. Computed tomography and endoscopy were performed at another hospital, and a biopsy was performed on a lesion suspected to be malignant. Biopsy revealed no remarkable findings other than lymphoid hyperplasia. Subsequently, IgG4-RD was confirmed via surgical biopsy. The disease and its symptoms were successfully treated with steroid therapy. |
