Higher incidence of rolled hairs in renal transplant recipients: a possible complication of corticosteroid and cyclosporine therapy.

Sir, Abnormal keratinization of the distal part of the hair follicle can prevent emergence of the growing hair from the follicle and lead to spiral growth within a hyperkeratotic papule, socalled ``rolled hairs'' (1). Rolled hairs have been reported in patients with keratosis pilaris (1), neurodermatitis (1), palmoplantar keratoderma (2), and hypertrichosis (3). The disorder has also been associated with corticosteroid therapy (1). Here we describe rolled hairs in renal transplant recipients and discuss the possible roles of prednisolone and cyclosporine in the pathogenesis of this condition.
