PG - e14121 LID - 10.1111/dth.14121 [doi] AB - Pyoderma gangrenosum (PG) is a rare neutrophilic dermatosis characterized by rapidly progressing necrolytic ulceration of the skin. Proper treatment is crucial since it can result in devastating consequences. First-line treatments include systemic corticosteroids or cyclosporine. However, no standardized treatment regimens for refractory cases exist and treatment outcomes are affected by underlying conditions. PG after cesarean section, which is believed to occur in association with underlying pregnancy- and parturition-related immune changes, is extremely rare, and all reported cases in the literature have been successfully treated with systemic or topical corticosteroids. We report a case of a 32-year-old patient with severe PG occurring on her cesarean scar 3 days after the cesarean delivery. Treatment with systemic corticosteroids and first-line immunomodulatory agents resulted in insufficient response and serious complications. Intravenous immunoglobulin (IVIG) was then initiated, and a rapid clinical response was seen. Corticosteroid dose was gradually decreased and ceased. IVIG infusion was continued for 3 months until complete recovery. Reactivation was not observed in a 1-year follow-up period. Due to its cost, IVIG infusion is less suitable as a first-line agent. However, IVIG may be an important therapeutic option in resistant postpartum PG, in which first-line agents have failed or led to complications. CI - (c) 2020 Wiley Periodicals LLC.
