Abstract

We report three elderly men with high serum IgG4 concentrations and multiple lymphoplasmacytic inflammation of the salivary glands, lymph nodes, pancreas, and renal interstitium. The infiltrating plasma cells had strong immunoreactivity for IgG4, even in patients without pancreatic lesions. These cases show that IgG4 is associated not only with autoimmune pancreatitis, but also with other systemic lymphoplasmacytic disease.
