Cystic Lung Disease in a Young man

Abstract

A 32-year-old man was admitted in the Emergency Department with acute dyspnea secondary to spontaneous pneumothorax. He had history of spontaneous pneumothorax 2 years ago.<br />He was active cigarette smoker (10 pack/year). The family history was unremarkable for lung diseases. Additionally, he had no systemic complaints.<br />The lung HRCT revealed multiple bizarre-shaped cysts distributed in both lungs with more severe involvement of upper and middle parts (Figure 1).<br />Since the HRCT findings were characteristic and he was smoker, the diagnosis of pulmonary langerhans cell histiocytosis (PLCH) was proposed. Small chest tube was inserted in left side and after 5 days it was easily removed.<br />He was recommended to quit smoking and close follow-up.
