Systemic lupus erythematosus with polyglandular autoimmune syndrome type II: report of an unusual case.

A patient with systemic lupus erythematosus (SLE) is described who had associated autoimmune thyroiditis with subclinical hypothyroidism and idiopathic Addison's disease. The presence of autoimmune thyroid disease and Addison's disease could classify her as having polyglandular autoimmune syndrome (PGAS) type II, which is the commonest of the three types of this syndrome. However, the additional presence of SLE in PGAS type II has not been described earlier. This patient appears to be the first such case.
