Primary adrenal insufficiency (Addison's disease) may initially present with cutaneous hyperpigmentation. Addison's disease, when associated with autoimmune thyroid disease and/or insulin-dependent diabetes mellitus, is referred to as polyglandular autoimmune syndrome type II. We present the case of a patient who initially was diagnosed as having Grave's disease and eventually Addison's disease due to persistent cutaneous hyperpigmentation, fatigue, weight loss, hypotension, hyponatremia, peripheral eosinophilia, and positive results of a synthetic corticotropin stimulation test. Addison's disease, polyglandular autoimmune syndrome type II, and cutaneous hyperpigmentation are reviewed.

Vitiligo is a depigmenting disorder characterized by the development of white patches with evidence in favour of an autoimmune mechanism. We investigated the role of melanotropins and the plasma levels of alpha-melanotropin and ACTH-like immunoreactivities in 40 vitiligo patients with the aim of detecting a possible influence of neuropeptide regulation of immunity. Twenty-one patients had active and 19 had stable vitiligo disease, 16 persons presented with an additional autoimmune thyroid disease. Median alpha-MSH levels in vitiligo patients were 6.4p mol/l [5.2;11.3] and significantly lower than in control persons with 11.4 pmol/l [8.6;13.4]. Median ACTH levels of the affected patient group were 17 pg/ml [10.5;28] and appeared statistically higher than 12 pg/ml [7;17] measured in the control group. Measured morning cortisol levels in both groups were not significantly different. Reduced cutaneous alpha-MSH immunoreactivities have been related to the development of autoimmune-induced depigmenting disorders. Our data present lower alpha-MSH plasma levels in vitiligo patients which may be associated with the development of vitiligo depigmentation and may indicate a condition of impaired peripheral tolerance in this autoimmune disorder.

Autoimmune polyglandular syndrome (APs) type 2 is characterized by the presence of Addison's disease, in association with autoimmune thyroid disease and/or type 1 diabetes mellitus and is rare in children. A 12.5 yr old prepubertal boy presented with symptoms related to Addison's disease and a large goiter. He was euthyroid with positive thyroid antibodies, low cortisol, aldosterone and very high adrenocorticotropin (ActH) and renin levels. Growth hormone (GH) secretion and an MrI scan of the pituitary were normal. He was started on hydrocortisone, fludrocortisone and subsequently on L thyroxine. Eighteen months later, decreased growth rate was noted and GH deficiency was detected, apparently secondary to autoimmune hypophysitis. Interestingly, he did not develop any other pituitary hormone deficiencies. He was started on GH therapy and had a good treatment response in the next 3 years. the combination of adrenal and thyroid insufficiencies with autoimmune hypophysitis is a very rare manifestation of APs-type 2. GH deficiency as the only symptom of lymphocytic hypophysitis is extremely rare. In children with autoimmune polyendocrine disorders, careful monitoring of growth is needed. In the case of low growth rate, GH should be evaluated by dynamic tests and, if GH deficiency is detected, treatment with hGH must be initiated.
