TLDR Trichoscopy can reveal specific hair and scalp changes in linear morphea.
A 7-year-old boy with a progressive linear plaque of alopecia on his scalp, forehead, and left eyebrow was diagnosed with morphea en coup de sabre, a form of localized scleroderma. Trichoscopy revealed pinpoint white dots, loss of follicular openings, peripilar casts, pili torti, and short regrowing hairs. Histology showed epidermal atrophy, hyalinization, and widening of dermal collagen bundles. Despite no neurological or ophthalmological issues, systemic immunosuppressive therapy with prednisolone and methotrexate was initiated due to plaque progression. This case is notable as the first detailed report of trichoscopy findings in linear morphea disease.
