The center of the patches remains covered with a firmly-adherent scale, which when raised shows projections from its under surfaceinto the dilated openings of underlying sebaceous glands. This central por-tion begins to undergo involution, the color fades, and an atrophy of theskin, which resembles a cicatrix, results. In this way circinate lesions areproduced, a red raised border, dotted with comedones, marking the linebetween atrophy and healthy tissue. As the border advances it may coverlarge surfaces, and, joining with others, form gyrate or serpiginous outlines.The resultant scar is thin, white, and smooth, never puckered. Where theprocess occurs upon hairy surfaces permanent alopecia inevitably remains.
