SARCOIDOSIS is considered a noncaseating and hence a noncavitating granulomatous process. Cavitary lesions are occasionally observed in sarcoidosis and have been ascribed to intercurrent fungal, tuberculous, or pyogenic infections.1-4 Concomitant bronchiectasis or bullous emphysema can also simulate cavitation, as shown on chest roentgenograms.5
Cavitation in pulmonary sarcoid granulomas has been previously reported.6-11 Since, however, specific studies to rule out known infectious causes of cavitating pulmonary granulomas were lacking or incomplete in these reports, the diagnosis of sarcoidosis may be challenged in all but one report.9
It is the purpose of this communication to report a case of cavitation of a pulmonary sarcoid granuloma. Bacteriologic and serologic studies adequately excluded the possibility of an infectious cause of this cavitary granuloma.
Report of a Case
