A 55-year-old male was introduced to our clinic in October 1987 because of an abnormal shadow in the left lung field. The infiltrate disappeared spontaneously and an another infiltrate appeared in his right upper lung field during the observation period. Since no eosinophilia was noted in the peripheral blood or bronchoalveolar lavage fluid, bronchiolitis obliterans organizing pneumonia (BOOP) was suspected and transbronchial lung biopsy (TBLB) was performed for confirmation. The pathologic finding was alveolitis with organizing pneumonia. We were unable to detect any obstructive findings in the bronchioli, since few bronchioli were obtained by TBLB. However, we diagnosed this case as BOOP on the basis of the clinical pictures. The infiltrate in the right lung showed a tendency to improve spontaneously and no therapy was performed. The shadow had disappeared almost completely by February 1988.
