Accuracy of Labial Salivary Gland Biopsy in Suspected Cases of Sjogren's Syndrome.

Introduction: Sjögren's syndrome (SS) is a chronic autoimmune disorder primarily characterized by dysfunction of the exocrine glands, leading to dryness of the eyes and mouth (sicca symptoms). Labial salivary gland biopsy (LSGB) is a key diagnostic tool used to confirm SS through histopathological analysis. LSGB evaluates lymphocytic infiltration in the salivary glands, a hallmark of SS.
