Triple-Negative Sjogren's Syndrome and Recurrent Pneumothorax: An Uncommon Presentation of Autoimmune Disease.

Sjogren's syndrome (SS) is a chronic exocrinopathy caused by lymphocytic infiltration and is associated with numerous manifestations and morbidities. We discuss a case of a 60-year-old female who presented to the Acute Medical Assessment Unit complaining of progressive shortness of breath for one month, not associated with chest pain or lower limb swelling. She also reported joint pain involving both wrists and proximal interphalangeal (PIP) joints, oral dryness, hair loss, and numerous tongue ulcerations.
