title: Obstructing tracheal pulmonary Langerhans cell histiocytosis.
abstract: Pulmonary Langerhans cell histiocytosis, also known as eosinophilic granuloma, is an uncommon interstitial lung disease. A solitary nodule, usually parenchymal, may rarely be the only manifestation of the disease. We describe a case of Langerhans cell histiocytosis presenting as an obstructing tracheal lesion in a 55-year-old woman. Following complete resection of the lesion via flexible bronchoscopy, full recovery was achieved. This case represents a unique cause for tracheal obstruction, as well as an unreported manifestation of pulmonary Langerhans cell histiocytosis.
