En coup de sabre is a rare form of localized scleroderma that presents as a linear, atrophic depression affecting the frontoparietal aspect of the face and scalp. Atrophy of en coup de sabre is a significant cosmetic problem for the patient. Surgical excision, autologous fat or bone grafting, and placement of synthetic tissue inserts have been performed with varing degrees of success. Recently, dermal filler treatments offer an attractive option as they are much less invasive and possess high efficacy in volumization compared to the aforementioned techniques.A 45-old-woman presented with 9-year history of asymptomatic linear vertical atrophic depression on right forehead extending from the glabella to the frontal part of the scalp. Associated alopecia was also noted. Intralesional injection of triamcinolone acetate 2.5mg/ml was tried during 6 months, but did not make any changes. Therefore, the patient was injected with 1ml of hyaluronic acid intradermally to correct the depression. The injections were well tolerated, and the patient did not experience any adverse effects. The patient expressed great satisfaction with the result. Herein, we report a case of en coup de sabre in which hyaluronic acid filler was successfully used to correct the atrophic defect.
