Lymphocytic interstitial pneumonitis presenting as recurrent pneumothoraces

A 34-year-old woman seronegative for the human immunodeficiency virus presented with recurrent, bilateral pneumothoraces. She also had bibasilar interstitial and alveolar infiltrates, and histologic examination was consistent with lymphocytic interstitial pneumonitis. To our knowledge, this is the first documented case of lymphocytic interstitial pneumonitis presenting with recurrent pneumothoraces.
