Tufted hair folliculitis (THF) was first noted in 1970, by Tagami et al. as numerous multiple hairs, and later in 1978 by Smith et al., termed as a tufted hair folliculitis (THF). Characterized by multiple hair tufts scattered within the patch, each tuft consist of 5 to 20 normal-appearing hairs arising from a single dilated follicular opening. They result in scarring alopecia with sclerotic, erythematous, shiny skin.
We report a case of THF, and will discuss the clinical features, phototrichogramical, histopatho- logic findings, treatments and possible pathogenesis.
