Pulmonary Langerhans'- cell histiocytosis belongs to a spectrum of diseases characterized by monoclonal proliferation and infiltration of organs by Langerhans'cells. It is an uncommon interstitial lung disease of unknown etiology occurring almost exclusively in cigarette smokers. It's course in adults is variable and unpredictable, ranging from benign self-limiting types with spontaneous regression to slowly progressive malignant disease that leads to respiratory failure and death. We report one patient diagnoses of pulmonary Langerhans'cell histiocytosis who experimented an objetive radiographic improvement and disappearance of symptoms after smoking cessation.
