We report a patient who suffered from bronchiolitis obliterans organizing pneumonia(BOOP) after Ivor Lewis operation for esophageal cancer. The patient presented low grade fever, dry cough and mild dyspnea at 4 day after operation. Chest roentgenograms and chest CT revealed bilateral patchy and infiltrative shadows. The respiratory symptoms worsened and respiratory failure developed with mild elevation of WBC count despite of conservative treatment. An open lung biopsy was done and the biopsy specimen showed bronchiolitis obliterans organizing pneumonia(BOOP). After several weeks of steroid therapy, there were marked clinical, physiological and roentgenographic improvements. Our experience suggests that BOOP may be one of the underlying pathology in a number of patients presenting with ARDS after thoracotomy. Since steroid therapy may improve survival in these patients, thoracic surgeons should heighten their index of suspicion for this entity. Early histologic diagnosis should be considered in patients with treatment-resistant ARDS after thoracotomy.

A case of dermatomyositis presented as bronchiolitis obliterans organizing pneumonia has been rarely reported. We describe a 46-year-old female patient with dermatomyositis without elevation of creatine kinase presented as bronchiolitis obliterans organizing pneumonia. She was treated with prednisolone and azathioprine. Over a 2-year follow-up she has had no elevation of creatine kinase. The patient remains asymptomatic and has no medication for dermatomyositis and bronchiolitis obliterans organizing pneumonia two years after initial treatment. It has been suggested that the prognosis of dermatomyositis without creatine kinase elevation may be poor. Because the prognosis of bronchiolitis obliterans organizing pneumonia is generally believed to be good, we tentatively suggest that the normal value of creatine kinase in dermatomyositis does not always seem to herald a poor prognosis, an associated malignancy or severe interstitial lung disease.
