Sweet's syndrome (acute febrile neutrophilic dermatosis) is characterized by inflammatory skin lesions accompanied by fever, leukocytosis and malaise, it should be recognized by hematologists, because it can be a paraneoplastic manifestation. Systemic involvement may be present and lung lesions, despite of the rarity, have been reported in the form of bilateral pulmonary infiltrations, bronchiolitis obliterans and pleural effusion. Histopathology shows dense neutrophilic infiltrates. We present a patient with chronic myeloid leukemia who developed Sweet's syndrome with bilateral pulmonary infiltrations, which were non-responsive to antibiotics but showed clinical improvement on steroid therapy.
