The authors report on the course seen in 7 cases of pulmonary histiocytosis X. In Group I (3 patients) immunosuppressive therapy was initiated on account of severe general symptoms and reduced pulmonary function. Remission was induced in 2 cases, whereas relapses occurred intermittently in one patient. ⋯ Progression did not occur with any of the patients. Pulmonary histiocytosis X should be treated with corticosteroid monotherapy in case of progressive deterioration of pulmonary function and/or if there are severe general symptoms. Chance findings in patients who are otherwise free from complaints should merely result in a closely meshed control checkup before taking any action.
