Presentation of case: We present a case report of a patient that debuts with dysphagia, with an abdominal computed axial tomography (CAT) scan revealing a mass at the gastro-esophageal junction suggestive of malignant origin, with studies revealing it to be Immunoglobulin G4-related (IgG4). Discussion: The diagnosis and identification of IgG4-related gastric pseudotumors is very complicated, often and most commonly an incidental diagnosis upon histologic analysis, as is the situation in this case. Conclusion: Understanding its clinical course and early diagnosis can reduce unwarranted surgical intervention in some patients with IgG4-related disease. © 2020 The Author(s) %I International Journal of Surgery Case Reports %T Immunoglobulin G4-related gastric pseudotumor – An impostor: Case report %R 10.1016/j.ijscr.2020.09.057 %~ Intellectum
