Necrobiosis lipoidica and isotretinoin: A case report

Abstract

A woman with type I diabetes and Hashimoto’s disease presented necrobiosis lipoidica at 15 years of age. Cyclosporine 100 mg/day was prescribed; however, an abscess in the inguinal region led to treatment interruption. Then, she tried dimethyl fumarate at increasing doses up to 120 mg/day. The lack of results led to the discontinuation of the therapy. The third attempt was isotretinoin 40 mg/day for eight months, with wound healing. Recently, after a knee scar repair surgery, necrobiosis lipoidica lesions appeared at the suture site. The patient received isotretinoin 40 mg/day again, and the lesion regressed in three months.
