Pneumothorax in sarcoidosis.

While sarcoidosis is a relatively common but often underdiagnosed disease, pneumothorax appears to be a rare clinical event observed mostly at the late stages of the disease course. The precise underlying mechanism of such complication is unclear and probably involves the formation of bullae due to bronchial obstruction and retraction-collapse of distracted lung tissue. Thoracoscopic bullectomy represent the preferred treatment option for recurrent pneumothoraces. The administration of corticosteroids for the treatment of pulmonary sarcoidosis may have a protecting effect for such recurrences, but remains a controversial issue.
