ミクリッツ病3例の検討 Three Cases of Mikulicz's Disease as an IgG4-related Disease
We reported three cases of Mikuhcz's disease. Mikulicz's disease was diagnosed by the following criteria: 1) symmetrical enlargement of the lacrimal and salivary glands lasting at least 3 months', 2) the lacrimal and salivary glands were microscopically involved in the infiltration of inflammatory cells, 3) sarcoidosis and other lymphoproliferative diseases were excluded. Three patients with Mikulicz's disease were all characterized by elevated IgG4 concentration in the serum and prominent infiltration of IgG4-positive plasmacytes in the minor salivary glands. On the contrary, there were no findings indicating sicca syndrome or anti-SS-A and SS-B antibodies, which characterize Sjögren syndrome. It is suggested that Mikulicz's disease is an IgG4-related plasmacytec disease, with a pathogenesis differing from that of Sjögren syndrome.
