A case of tufted hair folliculitis

A 35-year-old man developed red papules and plaques with alopecia and hair tufts on the parietal and occipital areas of his scalp. Each tuft was comprised of 5 to 25 hairs arising from individual hair follicules. Histopathological findings showed a dense infiltration of plasma cells in the dermis. Based on these findings, he was diagnosed as tufted hair folliculitis. Oral minocycline and topical gentamicin were not effective, but the patient responded well to four weeks of oral refampicin.
