REPORT OF A CASE
A 28-year-old white man was referred for evaluation of scarring alopecia of his scalp and possible folliculitis of his limbs and trunk. These problems had been present for more than 10 years. He received no benefit from prior use of various topical therapies. Seven years before presentation, he had been treated for a few weeks with oral vitamin A (50 000 U twice daily). Family history was significant for keratosis pilaris in his mother, sister, and several nieces and nephews. All family members have straight hair. The findings from the physical examination of his scalp revealed an 8-cm area of scarring alopecia with follicular scaling papules and pustules; the remainder of his scalp hair was excessively curly (Fig 1). On his trunk, arms, and legs were 1- to 2-mm erythematous follicular keratotic papules. Palms and soles showed mild diffuse keratotic thickening. Facial findings were significant for
