Sjögren's syndrome in children.

Sjögren's syndrome is a relatively uncommon condition in the pediatric age group. The clinical and immunological features of this disease in childhood have not been adequately described in the literature. Herein, we present details of the clinical features and results of laboratory investigations including minor salivary gland biopsy, parotid scintigraphy, and renal biopsy on two children with Sjögren's syndrome associated with systemic lupus erythematosus.
