Sweet syndrome is an acute reactive disorder characterized by the abrupt onset of skin lesions, dense infiltration of neutrophils in the dermis on skin biopsy and associated systemic features such as fever, leukocytosis, and increase
of C-reactive protein and erythrocyte sedimentation rate. The condition responds well to corticosteroid therapy. Most skin lesions are in the form of erythematous tender papules or nodules, while pustules are uncommon. We herein
report a rare case of a 57-year-old male with erythematous tender pustules on the face, finally diagnosed as pustular Sweet syndrome.
