An ulcerated gastric ulcer and pseudotumour with pancreatic affectation associated with immunoglobulin G4-related disease: a case report and literature review

Abstract

We report the case of a 67 year old male who presented with a nine year history of a gastric ulcer with symptoms of hematemesis and melena. Histological analysis identified fibrotic lesions and the accumulation of immunoglobulin G4-positive plasma cells with no evidence of malignancy. The lesion extended into the pancreas, where histological lesions and gastric lesions were also observed. This is a case of an ulcerated gastric ulcer and pseudo-tumor with pancreatic affection that is associated with immunoglobulin G4-related disease.
