Core Tip
Core Tip: Immunoglobulin G4-related disease is a fibrotic inflammatory disease that affects almost all organs and primarily occurs in middle-aged to elderly male patients. It can occur in the mediastinum, airways, lungs, and pleura and is most commonly associated with manifestations outside the chest, which are usually nonspecific. The prognostic characteristics have not yet been determined. Diagnosis relies on a thorough assessment of clinical, biological, and histological findings, as there are no specific biomarkers. Differential diagnoses must always be considered, especially when the disease affects a single organ, is incidentally found on imaging studies, or is unexpectedly diagnosed on pathological specimens.
