AUTOIMMUNE POLYGLANDULAR SYNDROME TYPE II AS A CAUSE OF RECURRENT CARDIAC TAMPONADE

Objective: This study reports an unusual presentation of autoimmune polyglandular syndrome type II (APS II) with recurrent cardiac tamponade due to pericarditis in a young male patient. Method: We report clinical presentation, laboratory data, and imaging studies for our patient. Relevant literature is reviewed.

His morning serum cortisol lev...
