INTRODUCTION: Immunoglobulin G4-related disease (IgG4-RD) rarely involves the esophagus, typically causing stenosis that presents significant diagnostic and therapeutic challenges. Due to its rarity and its mimicry of other conditions, obtaining a definitive preoperative diagnosis can be difficult. This report details a case of IgG4-RD-induced esophageal stenosis with initial diagnostic ambiguity, which was successfully managed with mediastinoscopy-assisted esophagectomy (MAE), highlighting this minimally invasive approach in a patient with comorbidities.
CASE PRESENTATION: A 70-year-old male with comorbidities, including obstructive pulmonary disorder, presented with progressive dysphagia and epigastric discomfort. Endoscopy revealed a persistent mid-esophageal ulcer and a non-passable circumferential stricture; multiple biopsies were nondiagnostic for malignancy or infection. Given the refractory nature of the stenosis, MAE with gastric conduit reconstruction was performed. The postoperative course was uneventful, and the patient achieved symptom resolution without medication. Histopathological examination of the resected esophagus confirmed IgG4-RD, showing obliterative phlebitis and a dense infiltrate of IgG4-positive plasma cells (80/high-power field; IgG4/IgG ratio 80/85).
CONCLUSIONS: This case underscores that IgG4-RD should be considered in the differential diagnosis of refractory esophageal stenosis, even with initially inconclusive biopsies. While serum IgG4 measurement has low sensitivity, it is still recommended. For benign esophageal stenosis of unclear etiology, particularly in patients with significant comorbidities, MAE can be a useful and potentially curative surgical option, offering symptom resolution and the possibility of a drug-free outcome.
