title: Pneumothorax as a presenting manifestation of early sarcoidosis.
abstract: Pneumothorax rarely develops sarcoidosis. A 21-year-old man with early sarcoidosis presenting as pneumothorax is reported. The patient came to our institute with severe chest pain and dyspnea. Plain chest roentgenograms revealed pneumothorax in the left lung. A chest tube was inserted to inflate the lung. Subsequent computed tomography demonstrated subpleural blebs in the upper lobe of the left lung. Continuous treatment with tube drainage was performed. However, surgical intervention was needed since long-term tube drainage turned out to be unsuccessful. Thoracoscopic partial extirpation on the left upper lobe was performed. The histology of the obtained lung tissue showed non-caseating granulomas composed of epithelioid cells and occasional giant cells. A diagnosis of sarcoidosis was made on the basis of the histological report. Although early sarcoidosis presenting as pneumothorax is rare in young patients, the possibility of a sarcoidosis should be considered.
