title: Steroid-responsive pulmonary hypertension in a patient with Langerhans' cell granulomatosis (histiocytosis X).
abstract: We report the case of a man with biopsy-proved pulmonary Langerhans' cell granulomatosis (histiocytosis X) and pulmonary precapillary hypertension. Pulmonary vascular resistances and mean pulmonary artery pressure decreased with corticosteroid therapy and dyspnea improved.
