[POEMS syndrome with primary adrenocortical insufficiency].

BACKGROUND: POEMS syndrome is a multisystem disorder. It usually presents as severe polyneuropathy and monoclonal gammapathy associated with endocrinopathies, organomegaly, skin hyperpigmentation. CASE REPORT: A patient with POEMS syndrome developed primary adrenocortical deficiency revelated by asthenia and hyperpigmentation. Hydrocortisone replacement therapy produced a rapidly beneficial effect on asthenia and hyperpigmentation. DISCUSSION: Although asthenia and skin pigmentation are common in POEMS syndrome, adrenocortical deficiency is seldom reported. This endocrinopathy might be underestimated in POEMS patients. We suggest systematic screening with a rapid ACTH test in all POEMS patients in order to detect underlying adrenal deficiency.
