title: Idiopathic pulmonary hemosiderosis. Electron microscopic, immunofluorescent, and iron kinetic studies.
abstract: The clinical course of a 37-year-old white man with idiopathic pulmonary hemosiderosis is presented. This patient is unusual in that he has had repeated exacerbations and remissions over a period of seven years and remains currently in spontaneous remission with no therapy. Routine sections of the lung biopsy revealed characteristec findings. Immunofluorescence staining of the lung was negative, and electron microscopic studies showed only nonspecific findings. While in remission, 51chromium-labelled red-blood-cell survival studies and 59iron kinetic studies were performed; the results were normal.
