Cushing syndrome caused by topical corticosteroid: a case report.

Development of iatrogenic Cushing syndrome from topical steroid therapy is very rare in adults. A 48-year-old woman with a diagnosis of Cushing syndrome caused by long-term topical clobetasol propionate application was presented. Laboratory studies were consistent with adrenal suppression that improved after discontinuation of the use of topical glucocorticoids. Patients who will take treatment with steroids, even with topical steroids, should be offered information about the dose, duration, and type of the treatment and its systemic side-effects.
