A rare renal disease occurring in the setting of a systemic IgG4 related disease (IgG4-RD). The disorder is characterized by a fibrosing tubulointerstitial nephritis consisting of predominantly IgG4+ plasma cells with/without glomerulonephritis, retroperitoneal fibrosis and hydronephrosis. |

A rare systemic autoimmune disease characterized by infiltrates of IgG4-positive plasma cells and lymphocytes in the adventitia of the aorta, resulting in thickening of perivascular tissue or formation of soft tissue masses surrounding the aorta and its major branches (potentially complicated by inflammatory aortic aneurysm), associated with elevated serum IgG4 levels. Preferential location is the infra-renal portion of the abdominal aorta. In addition, medium-sized blood vessels can be involved, and the condition may occur together with IgG4-related disease in other parts of the body. Clinical symptoms are unspecific and include chest or back pain and fever. |

A rare, brain inflammatory disease characterized by thickening of the dura mater of the cranium or spine with at least two histopathological features of IgG4-related disease: dense lymphoplasmacytic infiltrate, storiform fibrosis, and/or obliterative phlebitis. Patients typically have non-specific CSF findings and might be without systemic involvement or serum IgG4 elevation. Clinical manifestations are caused by mechanical compression of nerve or vascular structure, leading to functional deficit, most commonly headache, cranial nerve palsies, vision problems and motor weakness. |

|
A rare, inflammatory eye disease characterized by IgG4-immunopositive lymphocyte and plasmacyte infiltration and collagenous fibrosis of affected tissue and elevated serum levels of IgG4. Clinical presentation includes mass lesion or swelling of the involved structures, commonly involving lacrimal gland and duct, infraorbital and supraorbital nerves, extraocular muscles and orbital soft tissues. A systemic involvement is common. |

A clinical disease characterized by elevated serum IgG4 concentration and tumefaction or tissue infiltration by IgG4-positive plasma cells. |

A rare otorhinolaryngologic disease characterized by an indolent submucosal mass of variable size and extent, most commonly arising in the anterior nasal cavity, involving the nasal septum and lateral nasal wall, and potentially extending into the adjacent sinuses. Occurrence in the larynx and lower respiratory tract or the orbit is rare. Histological examination shows concentric angiocentric stromal fibrosis (onionskin fibrosis) and prominent eosinophils. Increased numbers of IgG4-positive plasma cells in the lesion may also be observed, in addition to elevated serum IgG4. Patients typically present with long-standing obstructive symptoms. |

Some |
|
A rare IgG4-related disease characterized by a benign tumor-like chronic inflammatory lesion of the submandibular gland. Histologic features are periductal fibrosis, acinar atrophy, obliterative phlebitis, dense lymphoplasmacytic infiltrates rich in IgG4-positive plasma cells, and formation of lymphoid follicles. Lobular architecture is preserved. Patients most commonly present with unilateral, painless swelling of the submandibular gland. Serologic analysis reveals elevated IgG4 levels. |
