Biopsy-proven IgG4-related lung disease

Biopsy-proven IgG4-related lung disease

BACKGROUND Immunoglobulin G4-related disease (IgG4-RD) is a fibroinflammatory disorder that may involve single or multiple organs. Biopsy-proven lung involvement of this disease is occasionally reported, but not well understood. METHODS Patients with the diagnosis of biopsy-proven IgG4-related lung disease (IgG4-RLD) from Peking Union Medical College Hospital between January 2011 and July 201...

IgG4 Related Lung Disease

IgG4 related disease is a poorly understood immune mediated condition. Lung involvement is rare and difficult to diagnose and can mimic primary lung malignancy on imaging. A patient who was found to have an incidental lung lesion with risk factors for primary pulmonary malignancy is reported.

Isolated IgG4-related interstitial lung disease: unusual histological and radiological features of a pathologically proven case

IgG4-related lung disease is commonly associated with autoimmune pancreatitis. Recently, isolated IgG4-related interstitial lung disease (ILD) without other organ involvement has newly been reported in two cases with clinical features of nonspecific interstitial pneumonitis (NSIP).We report the first case of an isolated IgG4-related ILD in a 78-year-old man with dry cough and dyspnea, whose cli...

Pulmonary schistosomiasis mimicking IgG4‐related lung disease

IgG4-related disease (IgG4-RD) is a systemic fibroinflammatory disease characterized by tumefactive lesions in various organ systems, including the lungs. Clinical and radiological manifestations of IgG4-RD are relatively non-specific, and we report a case highlighting the importance of histopathological confirmation in cases of suspected IgG4-related lung disease. A 44-year-old male with signi...
