Abbreviations
- IgG4-related disease (IgG4-RD)
Synonyms
- Historical terms in various locations include Küttner tumor (submandibular gland), Mikuliçz syndrome (parotid & submandibular), Riedel thyroiditis
- Orbit involvement previously grouped with nonspecific idiopathic orbital inflammation [(IOI), a.k.a. pseudotumor] but now recognized as separate entity
- Skull base "pseudotumor" can be due to IgG4-RD
Definitions
- Systemic immune-mediated disease with fibroinflammatory lesions at nearly any anatomic site (likely autoimmune)
- Requires clinical, radiologic, serologic, & histopathologic correlation; immunohistochemistry has improved characterization of this disease
