Trichoscopic Features of Linear Morphea on the Scalp.

Linear scleroderma en coup de sabre (LSCS) is the most common form of morphea on the scalp and its trichoscopic features have not been described yet. We report 2 adult women with LSCS with distinct dermoscopic findings. They both had an atrophic well-defined linear patch of alopecia on the frontotemporal scalp. Dermoscopy showed loss of follicular openings on a whitish skin surface; scattered black dots, broken hairs, and pili torti; and short thick linear and branching tortuous vessels on the periphery of the lesion. Pathology confirmed the diagnosis of LSCS in the 2 cases. This description of dermoscopic features in LSCS on the scalp may help in the early diagnosis of the disease.
