Bronchial lavage fluid on the 2nd day after lung transplantation. Different shapes of alveolar macrophages with blood cells (including erythrocytes, lymphocytes, neutrophils, and eosinophils). (a) The size of alveolar macrophages was varied, cytoplasm was moderate to rich, stained light blue to gray-blue, purple-red granules can be seen in some cytoplasm, nuclear chromatin varies in thickness, and nucleolus can be seen in some cells (Wright-Giemsa stain, x400). (b) Binuclear alveolar macrophages with vacuoles in some cells (Wright-Giemsa stain, x1000).

The morphology of all kinds of cells was normal [Figure 1].
Cytological examination of bronchial brush, 21 days after lung transplantation. There were a few columnar epithelial cells, some neutrophils, a few macrophages and erythrocytes, and a few yeast-like fungal spores. (a) A few columnar cells, some neutrophils, and necrotic components (Wright-Giemsa stain, x400). (b) Neutrophils, alveolar macrophages and fungal spores, and budding reproduction phenomenon can be seen (Wright-Giemsa stain, x1000).
