[Cushing syndrome following external glucocorticoid administration in psoriasis].

We report on a 20-year-old patient suffering from psoriasis vulgaris who treated himself with high dosages of powerful topical corticosteroids (250 mg desoxymethasone a week). He developed Cushing's syndrome which disappeared after discontinuation of that therapy. In general, these cases are rare because of the low percutaneous resorption of these glucocorticoids being below ten percent in most anatomical regions.
