Show answer and explanation
Correct answer: A. Sjögren syndrome
- A. Correct. The sicca complex — dry mouth (xerostomia) plus dry eyes (keratoconjunctivitis sicca) — is the defining presentation of Sjögren syndrome.
- B. Lupus is a multisystem autoimmune disease but does not classically present with the primary sicca complex.
- C. Rheumatoid arthritis can coexist with secondary Sjögren, but RA itself is a joint disease, not the cause of the dryness.
- D. Sarcoidosis can cause gland involvement but is not the classic dry-eyes/dry-mouth diagnosis.
