title: Patchy Traction Alopecia Mimicking Areata.
abstract: Acute traction alopecia is a diagnostic challenge when the external factor is not suspected or admitted. We report two female patients with non-scarring patchy alopecia resulting from traction of video-electroencephalogram electrodes in which the clinical diagnosis of alopecia areata was suspected. Associated diffuse hair disorders might be implicated in these cases. The correct diagnosis of traction alopecia is important in order to avoid unnecessary treatments.
