Follicular keratosis of the chin treated with 1.24R-dihydroxyvitamin D3 ointment.
In follicular keratosis of the chin, keratotic follicular papules occur on the chin and jaw due to localized prolonged pressure and friction on the naked skin. We present one patient with this disorder. The dermatoscopic examination revealed many well-demarcated yellow spindle bodies in the patchy lesion. Therapy with 1.24R-dihydroxyvitamin D3 ointment was effective during the treatment but had no residual positive effect.
