Tufted hair folliculitis developing in a recalcitrant lesion of pemphigus vulgaris.

We describe tufted hair folliculitis that developed in a chronically erosive plaque on the scalp of a Japanese man patient with pemphigus vulgaris. After repeated intralesional corticosteroid injections, the erosive lesion improved, leaving multiple hairs emerging from single follicular openings. The current case suggests that localized exudative inflammatory lesions in the scalp regardless of cause can result in tufted hair formation.
