Clinical, Imaging, and Laboratory Findings in Sjögren's Syndrome.

Sjögren's syndrome (SS) is a rare condition characterized by structural damage and secretory dysfunction of the lacrimal and salivary glands that leads to dryness, particularly xerophthalmia (eyes) and xerostomia (mouth). No cure is known; however, the effects of the disease are manageable and symptoms may be reduced. Although the salivary damage is irreversible, the dental decay and oral infections may be prevented, which highlights the importance that the clinician plays in the diagnosis and management of SS. The cardinal features of this disease are summarized through the case report of primary SS in a 23-year-old woman who received an early diagnosis based on clinical features, laboratory investigations, lower lip biopsy, and imaging findings.
