Question: What diseases should be considered in a 15-year-old girl presenting enlarged lacrimal and salivary glands?
Finding: Laboratory tests revealed elevated IgG4 levels. A submandibular gland biopsy showed lymphoplasmacytic infiltration and more than 40 immunoglobulin G4 (IgG4)-positive cells per high-power field. The patient was diagnosed with IgG4-related disease.
Meaning: Although rare in children, IgG4-related disease should be considered a differential diagnosis in children with enlarged salivary and lacrimal glands. |
