Gastrointestinal and liver lesions in primary childhood Sjögren syndrome.

Sjögren syndrome (SS) is characterized by lymphocytic infiltration of exocrine glands, mainly the lacrimal and salivary glands, leading to keratoconjunctivitis sicca and xerostomia. SS is one of the most common autoimmune rheumatic diseases in adults; however, few cases of primary childhood SS with gastrointestinal and liver lesions have been reported in the literature. We report five cases of primary childhood SS with gastrointestinal and liver lesions. Multiple gastric biopsies in four cases revealed atrophic gastritis in the antrum of the stomach or chronic gastritis. Liver biopsies in two cases revealed nonalcoholic steatohepatitis. Careful clinical approach and follow-up for gastrointestinal and liver lesions are required.
