| Abstract |
|
Mikulicz’s disease is an immunoglobulin G4-related systemic disease involving enlargement of the lacrimal and salivary glands that differs substantially from Sjögren’s syndrome. A 45-year-old woman who noticed bilateral swelling in the submandibular region and dry mouth for 6 months was admitted. Ultrasonography of the enlarged glands revealed an irregular, hypoechoic, multilobular mass, and the power Doppler showed that the mass was hypervascular. She had an elevated immunoglobulin G level, positive Schirmer’s I test, and positive unstimulated whole salivary flow test, but was negative for antinuclear, anti-Ro/SS-A, and anti-La/SS-B antibodies. The submandibular gland biopsy showed diffuse infiltration of lymphocytes and plasma cells expressing immunoglobulin G4. We report a patient diagnosed with Mikulicz’s disease involving the infiltration of plasma cells expressing immunoglobulin G4 and unique ultrasonographic findings. |
