Psoriasis affects both nail matrix and nail bed. Pitting, leukonychia and red spots in lunula indicate a defect in the nail matrix.

The purpose of the study is to evaluate the efficacy and safety of intralesional triamcinolone comparing to 0.05% clobetasol ointment in the treatment of psoriatic nails.
