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.
