IgG4 related disease (IgG4-RD) is probably an autoimmune pathology of unknown etiology. Diverse interactions participate in its pathogen between the adaptive and innate immune systems, activating lymphocytes B and T which trigger the inflammatory cascade, which culminates in fibrosis of the organs and their malfunction Common features include IgG4-related autoimmune pancreatitis, swelling of or within an organ system (an inflammatory pseudotumor), salivary gland disease (which can lead to enlargement of the salivary glands), swollen lymph nodes (lymphadenopathy), skin manifestations, and symptoms consistent with allergies or asthma

IgG4-related disease has been identified in various organs, but whether or not there are organ-specific characteristics related to the etiologic factors is still unknown.

This case showed many clinical findings, such as bilateral swelling of salivary and lacrimal glands, autoimmune pancreatitis, interstitial nephritis, retroperitoneal fibrosis, periaortitis, systemic swelling of lymph nodes, pulmonary lesions, splenomegaly, and jejunal lesions IgG4-related disease was not recognized as a specific clinical entity until 2003 when extrapancreatic lesions were reported in patients with autoimmune pancreatitis. IgG4-related disease is characterized by elevated serum IgG4 levels and infiltration of the target organ by IgG4-positive plasma cells IgG4-related disease (IgG4-RD), a recently recognized systemic inflammatory disorder, generally presents as a mass-forming lesion, or lesions, or organ enlargement . Clinical symptoms are diverse depending on the combination of organs affected, but most patients have only mild or no symptoms IgG4-related disease is its excellent response to corticosteroid therapy. The head and neck are commonly involved in IgG4-related disease. Manifestations may occur anywhere in the head and neck; how-ever, the disease most commonly involves the salivary glands, lacrimal glands, orbits, thyroid gland, lymph nodes, sinonasal cavities, an IgG4-related disease of the central and peripheral nervous systems.

He was largely asymptomatic but had bilateral salivary and lacrimal gland enlargement. A grossly elevated serum IgG (>70 g/L) with concomitant suppression of other immunoglobulins, a small IgG restriction, and a parotid biopsy revealing.
