Facial lichen striatus: successful treatment with tacrolimus ointment

We report a 22-year-old Japanese woman with facial lichen striatus (LS). The distribution of the lesions corresponded to that of Blaschko's lines. Histology of the lesional skin showed an inflammatory cell infiltrate around hair follicles and eccrine glands. Treatment of the linear lesions with tacrolimus ointment once or twice daily resulted in a dramatical improvement in a short time. LS is a T-cell-mediated inflammatory disease and tacrolimus ointment may be an effective alternative treatment for this disease especially when the lesions are located on the face.
