Sjögren syndrome (SS) is a common disorder in adults and involves both glandular and extraglandular systems. We report here four cases of childhood SS complicated by chronic thyroiditis, interstitial nephritis or sweat gland inflammation. Additionally, in one of these cases, the central nervous system was involved. All of these complications are common in adult cases.
Childhood SS is a systemic "ductilitis" or "exocrinopathy" with complications which are commonly observed in adult cases.
