En coup de sabre

En coup de sabre (ECDS) is a rare form of localized scleroderma that typically manifests in children and women. It presents as a fibrous pansclerotic plaque extending in a bandlike distribution on the frontoparietal scalp with surrounding scarring alopecia. Many patients have comorbid central nervous system involvement in addition to the cutaneous findings. En coup de sabre is a rare entity that should be delineated from Parry-Romberg syndrome, as both entities share some common features and may coexist. Corticosteroids remain the treatment of choice, but other modalities such as methotrexate, excimer laser, and grafting have been used with varying success. We report a case of an elderly woman who presented with an asymptomatic alopecic plaque consistent with ECDS.
