Abstract
Acute febrile neutrophilic dermatosis (AFND) (Sweet''s syndrome) is characterized by warm, erythematous plaques, accompanied by arthralgias, fever and leukocytosis. A 53-yr-old man was seen with chronic, recurrent and unusually persistent AFND. The patient had a history of a gastrojejunostomy for peptic ulcer disease and had symptoms of the blind loop syndrome. Medical therapy for the blind loop syndrome failed to control his skin lesions, fever or leukocytosis. His symptoms responded to prednisolone therapy. The relationship of AFND to the bowel bypass syndrome is discussed.
