[Morphologic diagnosis of pulmonary hemorrhage]

Abstract

The gross and histologic morphologic features of early and advanced pulmonary hemorrhages are easy to recognize. Although there is no close correlation between the hemorrhagic appearance of the bronchoalveolar lavage fluid, the histologic features of hemorrhage, and the score of hemosiderin in alveolar macrophages, studies of bronchoalveolar lavage fluid samples are valuable for diagnosing and monitoring pulmonary hemorrhages.
