Primary juvenile Sjögren's syndrome.

Primary Sjögren's syndrome has rarely been reported in children. We report 3 patients who developed lacrimal and salivary gland involvement at ages 3, 7 and 9, respectively. The one who began at age 3 is the youngest we could find reported. Sjögren's syndrome-type involvement was documented objectively at both sites and associated connective tissue diseases were ruled out in all 3 patients.
