Keratosis lichenoides chronica. Successful treatment with psoralen-ultraviolet-A therapy.
A man with keratosis lichenoides chronica is described who, unlike previously described patients, had had his eruption since infancy. Moreover, this patient had prominent oral involvement resembling lichen planus. Typically, keratosis lichenoides chronica is recalcitrant to all forms of treatment, but this patient responded substantially to psoralen-ultraviolet-A therapy. Several weeks after treatment was completed, he showed no signs of relapse.
