title: Spectrum of Sjögren syndrome in children.
abstract: Sjögren syndrome, consisting of keratoconjunctivitis sicca and xerostomia with or without another autoimmune disease, is uncommon in children. We describe our retrospective experience with eight pediatric patients with SS. All had recurrent parotid enlargement and abnormal salivary gland biopsies, six had keratoconjunctivitis sicca, and five had other autoimmune manifestations, although only two of these had other clearly defined autoimmune disorders (mixed connective tissue disease and hypergammaglobulinemic purpura). Our patients had a higher incidence of primary SS, parotid enlargement, and hematologic abnormalities than did children previously reported with SS. Children with SS demonstrate a clinical heterogeneity comparable to that seen in adults.
