Abstract

Highlights: Gastric pseudotumors are rare entities that resemble gastric neoplasias and often unrecognized. Suggestive malignant gastric masses can in fact result IgG4-related pseudotumors. Gastric pseudotumors are often an incidental diagnosis upon histologic analysis after surgical resection. Understanding gastric pseudotumors can reduce unwarranted surgical intervention. Abstract: Introduction: Gastric pseudotumors are rare entities whose clinical presentation resembles typical gastric neoplasias, often making them unrecognized unless other causes are considered. 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.
