title: [A case of lung sarcoidosis which was clinically difficult to distinguish from hypersensitivity pneumonitis].
abstract: A case of pulmonary sarcoidosis (stage III), in which the abnormal chest shadow disappeared within two weeks was reported. A 35-year-old male was admitted for further examination of bronchial asthma. He stayed overnight at home after he received inhalation provocation test of sulpyrin. Returning to the hospital, he had a fever (38 degrees C) with diffuse small nodular shadows on the chest roentgenogram. The onset and clinical features of the disease suggested hypersensitivity or drug induced pneumonitis rather than sarcoidosis. Bronchoalveolar lavage fluid (BALF) analysis showed an increase of total cell counts and lymphocytes. The surface marker of lymphocytes in BALF revealed that the CD4/8 ratio was remarkably elevated to 6.2. Both transbronchial lung and scalene node biopsy specimens revealed numerous non-caseous granulomas, and a diagnosis of sarcoidosis was confirmed. The chest infiltrates disappeared spontaneously within two weeks. This case was reported because of its rare natural course as stage III pulmonary sarcoidosis.
