title: [Unusual pulmonary presentation of systemic Langerhans cell histiocytosis].
abstract: An 80-year-old nonsmoking man was referred to our hospital with bilateral perihilar pulmonary opacities. He had a history of epilepsy, sclerosing cholangitis, cutaneous lesions previously diagnosed as localised Langerhans cell histiocytosis. Symptoms included dry cough and dyspnea. Chest CT showed bilateral perihilar alveolar consolidation with bronchiectasis. Histological examination of a lung biopsy showed typical features of Langerhans cell granulomatosis. Investigations revealed anterior and posterior hypopituitarism. An important improvement occurred with corticosteroid and vinblastine treatment.
