- A disease of the scalp that may affect the glabrous skin and the nails and is recognized by the concave sulfur-yellow crusts that form around loose, wiry hairs. Atrophy ensues, leaving a smooth, glossy, thin, paper-white patch. This type of disease is rare in the United States and more frequently seen in the middle east, africa, southeastern europe, and other countries bordering the mediterranean sea.
