A number of reports show success with surgical repigmentation procedures, as well. Although we are making progress in treating this vexing disease (especially with calcineurin inhibitors and phototherapy), we still have a long way to go. At best, 75% of patients respond, and in most instances, this response is only partial. A breakthrough in the management of this disease would be greatly welcomed by both patients and doctors.
