Abstract:
Pulmonary Langerhans cell histiocytosis is a rare lung disease, which was previously classified as interstitial lung disease but is now classified as a myeloid neoplasm. The obstructing tracheobronchial lesion or mass may rarely be the manifestation of the disease. We describe a case of pulmonary Langerhans cell histiocytosis presenting as multiple obstructing bronchial lesions and pulmonary masses in a 36-year-old man. This case represents an extremely rare manifestation of pulmonary Langerhans cell histiocytosis.
