title: Sarcoidosis Mimicking Sjögren's Syndrome: Histopathologic Observations.
abstract: The clinical manifestations of Sjõgren's syndrome (SS) and sarcoidosis can be identical. Of the 1600 patients whom we have evaluated for dryness of the mouth and eyes, 300 proved to have SS and 5 had sarcoidosis. The patients with sarcoidosis had combinations of salivary gland enlargement, elevated antinuclear antibody titers, reduced salivary flow rates, and keratoconjunctivitis sicca, findings typically associated with SS. Finding non-caseating granulomas in a labial salivary gland biopsy specimen may be the only way to definitively differentiate these two disorders.
