Lichen Planopilaris Versus Discoid Lupus Erythematosus: A Trichoscopic Perspective
A 50-year-old male presented with lesions on the scalp since 4 months. History of exacerbation of lesions on sunlight exposure was present. Examination revealed erythematous scaly plaques on the vertex and frontal areas with atrophy of underlying skin [].\nTrichoscopy showed branching capillaries (yellow diamond), white patches (yellow star), keratin plugs (red arrow), reduced follicular ostia and white dots (red stars). Blue-grey dots (yellow arrow) inside the patch of alopecia referred to as “speckles” pattern were also observed []. Histopathology showed thinning of epidermis, hypogranulosis, follicular horny plugs, vacuolar changes and necrotic keratinocytes at the dermoepidermal interface which are consistent with diagnosis of DLE [].\nSystemic examination and blood investigations in both patients were unremarkable.
