Released: 2021-11-24
A man in his 50s presented to our dermatology department with an asymptomatic, arc-shaped, depressed skin groove on the left side of his forehead, frontal scalp, and vertex area. Localized linear hair loss and hair thinning on the left scalp area were observed. The patient reported that when the lesion had begun to appear, approximately 10 years earlier, he had received 2 doses of intralesional steroid via injection on a small bald patch on the vertex. Thereafter, the lesion gradually progressed to the frontal scalp and eventually made a linear furrow on the left side of his forehead.
