Abstract
Three similar cases were previously reported characterized by typical follicular changes different from those observed in hypertrichosis or pilar keratosis. This rare cutaneous side effect may be explained by the direct action of cyclosporine on the pilosebaceous unit: this drug is known to extend the anagen phase of the follicular cycle and to induce toxic follicular dystrophy at higher tissue concentrations. This particular toxicity is usually seen after many months of treatment. In our patient, the time to onset was shorter, probably due to occasionally excessive plasma concentrations.
