Pneumothorax, Primary Spontaneous

Primary spontaneous pneumothorax (PSP), or collapsed lung, results from the presence of air in the pleural space in the absence of a precipitating event such as trauma or lung disease. Affected individuals have subpleural blebs or bullae in the lungs (localized emphysema-like changes) that are associated with destruction of lung tissue. The majority of cases are sporadic. Isolated familial PSP is rarer, and has been associated with mutations in the FLCN gene in a small number of families.
