Adrenal crisis skin finding?

Adrenal crisis skin finding?

• A. Jaundice
• B. Pallor
• C. Erythema
• D. Hyperpigmented skin

Answer: (D)

Adrenal crisis from primary adrenal insufficiency leads to very high ACTH levels because cortisol is so low that the pituitary keeps pumping it out. ACTH shares a common precursor with melanocyte-stimulating hormone, so the increased ACTH drives melanocyte activity and causes skin darkening. This hyperpigmentation tends to be diffuse and can involve sun-exposed areas, skin folds, and mucous membranes, reflecting the chronic nature of the underlying deficiency rather than an acute inflammatory process. In contrast, jaundice points to liver/Biliary problems, pallor is nonspecific and more related to shock or anemia, and erythema signals inflammation. Hyperpigmented skin best fits the pattern seen with primary adrenal insufficiency and adrenal crisis.
