title: Acute pustular psoriasis complicated by leukocytoclastic vasculitis.
abstract: Acute pustular psoriasis is characterized by fiery-red erythema followed by formation of pustules. Precipitating factors include drugs, infections, pregnancy, solar irradiation, and psychological stress. We present a case of a woman who developed acute onset of pustular psoriasis precipitated by hydroxychloroquine therapy and systemic steroids. The patient's course was complicated by leukocytoclastic vasculitis presumptively caused by levofloxacin.
