The IgG4-related systemic diseases, also IgG4-related diseases, are diseases characterized IgG4 positive plasma cells and fibrosis.[1]
- Lymphoplasmacytic sclerosing pancreatitis - a type of autoimmune pancreatitis.
- Retroperitoneal fibrosis.[2]
- Riedel's thyroiditis.
- Inflammatory pseudotumour,[2] also known as inflammatory myofibroblastic tumour (IMT); probably only a subset of IMT.[3]
- Sclerosing cholangitis[2] (IgG4-associated cholangitis[4]).
- Autoimmune pancreatitis (lymphoplasmacytic sclerosing pancreatitis).
- Others.
Microscopic
Features:[5]
- At least 10 IgG4 +ve plasma cells.†
- >40% of plasma cells IgG4 +ve.
Note:
†Minimum number dependent on anatomical site.[5]
