A resistant case of pemphigus gestationis successfully treated with cyclosporine.

Pemphigoid gestationis (PG) is a rare autoimmune blistering disease of pregnancy caused by antibasement membrane zone auto-antibodies. The usual clinical findings are multiple pruritic urticarial papules and plaques, target lesions, vesicles, and blisters that occur during the second and third trimesters of pregnancy or in the immediate postpartum period. The disease is often treated with topical corticosteroids and oral antihistaminics. In more severe cases, systemic corticosteroids are needed. Herein, we report a case of resistant PG that responded to treatment with cyclosporine.
