Psoriasis vulgaris and autoimmune polyendocrine syndrome type I: a case report.

Autoimmune polyglandular syndrome (APS) is a rarely diagnosed condition characterized by a combination of two or more organ-specific autoimmune diseases and divided into a very rare juvenile (APS type I) and a relatively common adult type (APS II-IV). The major components of APS-I are hypoparathyroidism, adrenal failure, and mucocutaneous candidiasis. In addition to the classic triad, many other autoimmune diseases could be associated with the syndrome. We report an adolescent patient with psoriasis vulgaris and APS-I.
