Overview

Overview

Autoimmune polyendocrine syndrome (APS) can be classified into APS type 1, APS type 2 and APS type 3 on the basis of organ involvement. APS type 1 commonly presents with mucocutaneous candidiasis, hypoparathyroidism and Addison’s disease. APS type 2 most commonly presents with Addison’s disease, autoimmune thyroiditis and diabetes mellitus type 1. APS type 3 usually presents with autoimmune thyroiditis, diabetes mellitus type 1 and pernicious anemia.
