Description
Summary:Keratosis pilaris atrophicans represents a group of rare diseases characterized by keratosis pilaris on the extensor surfaces, inflammation and atrophic scarring. The keratosis pilaris atrophicans spectrum includes ulerythema ophryogenes, atrophoderma vermiculatum and keratosis follicularis spinulosa decalvans. Folliculitis spinulosa decalvans is considered a variant of keratosis follicularis spinulosa decalvans, presenting with persistent pustules, keratotic papules and scarring alopecia. The treatment is challenging, with few cases reported in the literature. We report the case of a 20-year-old man with folliculitis spinulosa decalvans since childhood, which had worsened in the past 5 years, with frequent recurrences and a poor response to isotretinoin but with some improvement after acitretin.
