Exceptional Case Membranous nephropathy with monoclonal IgG4 deposits and associated IgG4-related lung disease
A 62-year-old woman was admitted for nephrotic syndrome and lung tumor. A renal biopsy showed membranous features of the glomeruli. Immunofluorescence studies revealed granular IgG4-κ deposits along with the glomerular basement membrane. Electron microscopy revealed granular electron-dense deposits. Further study denied multiple myeloma. Light microscopy of the resected lung tumor revealed IgG4...

متن کاملMembranous nephropathy with repeated flares in IgG4-related disease
IgG4-related disease (IgG4-RD) is associated with the infiltration of IgG4-positive plasma cells into various organs. Nephropathy of IgG4-RD is generally interstitial nephritis and glomerulonephritis is rare. We describe a case of membranous nephropathy (MN) without interstitial nephritis associated with IgG4-RD symptoms including lymphadenopathy and pulmonary and pleural lesions. Treatment wit...
متن کاملMitochondrial-dependent Autoimmunity in Membranous Nephropathy of IgG4-related Disease
The pathophysiology of glomerular lesions of membranous nephropathy (MN), including seldom-reported IgG4-related disease, is still elusive. Unlike in idiopathic MN where IgG4 prevails, in this patient IgG3 was predominant in glomerular deposits in the absence of circulating anti-phospholipase A2 receptor antibodies, suggesting a distinct pathologic process. Here we documented that IgG4 retrieve...
متن کاملIgG4 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.
