title: [A case of pulmonary sarcoidosis with multiple cavitation and pneumothorax].
abstract: We describe a rare case of pulmonary sarcoidosis with multiple cavitation and pneumothorax. A 32-year-old woman was admitted to our hospital with a dry cough and an interstitial shadow with dense infiltrates in both upper lungs and cavitation in the right upper lung on chest roentgenogram and CT. Laboratory tests revealed an elevated level of serum lysozyme. BAL fluid demonstrated a high proportion of lymphocytes with an increased CD4/CD8 ratio, compatible with sarcoidosis. Transbronchial lung and skin biopsies showed evidence of noncaseating epithelioid-cell granuloma, and a diagnosis of sarcoidosis was made. Although pneumothorax appeared in the left lung on chest roentgenogram during clinical observation conservative treatment without corticosteroids or any other therapy for a follow-up period of 3 years resulted in improvement of her clinical condition and abnormal X-ray findings.
