A 19-year-old man visited our hospital complaining of cough, sputum and low-grade fever. Chest radiograph and computed tomography findings suggested that he was suffering from pulmonary Langerhans' cell histiocytosis (PLCH). Bronchoscopy revealed a whitish elevated lesion at the bifurcation of the right upper lobe bronchus, and a specimen of this lesion showed the same pathological findings as pulmonary parenchymal lesions. Although there have been only a few reports of endobronchial LCH without pulmonary parenchymal lesions, this is, to our knowledge, the first case of PLCH with an endobronchial lesion, which was confirmed by bronchoscopy, and disappeared several months later.
