The rash in life-threatening metabolic and endocrine disorders

Recognizing the skin manifestations of metabolic and endocrine disorders, many of which may have potentially lethal complications, is important for dermatologists and other clinicians. The skin can be a window into a patient's internal health, and cutaneous manifestations can facilitate early diagnosis and intervention of potentially life-altering systemic disorders with associated morbidity and mortality. This contribution provides an overview of the diverse rashes associated with potentially lethal, acquired metabolic and endocrine disorders of the pituitary, thyroid, parathyroid, pancreas, adrenals, and blood, as well as neuroendocrine and nutritional disease.
