Abstract
Spiny follicular hyperkeratosis (SFH) is follicular flesh-colored hyperkeratotic spicules that are linked to different situations including drug reactions. Previously suspected drugs are BRAF inhibitors and cyclosporine. We described a 51-year-old psoriasis patient with SFH who had been using acitretin.
