Trichoscopy as an Additional Diagnostic Tool for Monitoring of Lichen planopilaris

Lichen planopilaris (LPP) is a rare inflammatory disorder selectively involving hair follicles and leading to scarring alopecia. This disease is clinically characterised by follicular hyperkeratosis, perifollicular erythema and permanent hair loss mainly on the scalp. A 34-year-old woman was admitted with hair loss and itching of the scalp. Based on clinical symptoms, trichoscopy and histological findings we diagnosed classic LPP. The patient was treated with topical corticosteroids, but this therapy was ineffective. The remission of the disease was achieved after 2 months treatment with hydroxychloroquine 200 mg twice daily. Trichoscopy can be used as an additional LPP diagnostic tool for the monitoring of inflammation associated with this disease.
