Impetigo herpetiformis is an uncommon pustular dermatosis that typically occurs during pregnancy. Clinically and histologically, it bears some resemblance to pustular psoriasis, and the two conditions are discussed within the same entity.1 Systemic glucocorticosteroids are widely used for the treatment, whereas cyclosporine was also used in one case after delivery.2 We herein report a case of impetigo herpetiformis that did not respond well to systemic corticosteroids and required cyclosporine administration.
