Tufted hair folliculitis: a pattern of scarring alopecia?

We present a patient with pemphigus vulgaris who, over the years, experienced the development of tufted hair folliculitis as a result of scalp involvement. Multiple hairs emerged from widely dilated follicular ostia surrounded by indurated, scarred skin. Histopathologic findings were typical for tufted hair folliculitis. We believe that because a specific host response to scalp injury might be crucial to the development of this rare disorder, it should be regarded as a type of scarring alopecia.
