Positive Antinuclear Antibody (ANA)-Negative Systemic Lupus Erythematosus (SLE) Presenting With Acute Pancreatitis

Systemic lupus erythematosus (SLE) is an autoimmune disease with multisystem involvement and most commonly affects women of childbearing age. Most of the patients, if not all, have positive antinuclear antibody (ANA) in their serum. ANA-negative SLE is extremely rare. Here, we present a case of a 15-year-old girl presenting with pancreatitis due to ANA-negative SLE.
