In black population, the skin-bleaching with cutaneous topical corticosteroids on a large body area is a widespread practice and is associated with numerous cutaneous complications. We report a 25-year-old Congolese woman who was admitted for weakness, arthralgias and abdominal pain. The association of a relative hyperpigmentation of the small joints of hands and feet with clinical features of hypercorticism led to suspect a chronic use of cutaneous topical steroids for skin-bleaching. On biological tests, plasma cortisol and corticotropin levels were undetectable and the short corticotropin (ACTH) stimulation test was negative, leading to the diagnosis of adrenal insufficiency complicating the chronic use of topical steroids. Clinical symptoms resolved with hydrocortisone therapy. One year later, the patient admitted a five-year continuous use of cutaneous topical steroids (betamethasone, 0.05%). Skin-bleaching through chronic use of cutaneous topical steroids, is a common practice in black women, and should be suspected in the presence of adrenal insufficiency with or without clinical features of hypercorticism, and conversely, skin-bleaching users should be tested for hypothalamo-pituitary-adrenal function. |
