About 80% of patients treated with cyclosporine develop cutaneous adverse effects.1 These include manifestations of excessive epithelial proliferation: hypertrichosis, gingival hypertrophy, hyperplastic pseudofolliculitis barbae, pilar keratosis, epidermal (follicular infundibular) cysts, sebaceous gland hyperplasia, and, as recently described,2 folliculodystrophy syndrome. We report a case of tufted folliculitis of the scalp in a patient who was treated with cyclosporine.
