Abstract

Primary alopecias of the scalp are divided into scarring and nonscarring types [1]. Scarring ­alopecias include: (a) lymphocytic (discoid lupus erythematosus [DLE], lichen planopilaris [LPP], pseudopelade of Brocq [PPB], central centrifugal cicatricial alopecia [CCCA]); (b) neutrophilic (dissecting folliculitis/cellulitis, folliculitis decalvans); and (c) combined (acne keloidalis) subtypes. Nonscarring alopecias include alopecia areata (AA), telogen effluvium, trichotillomania, traction alopecia, and androgenetic alopecia (AGA) [1]. The etiology of many of these disorders is unclear; although, a combination of genetic and environmental factors appears to contribute to the pathogenesis of several types of alopecia [2].
