| In the lumen of the cysts, eosinophilic or blue secretions were frequently seen, with sometimes targetoid secretion. |
| Case 49 showed ductal structures mixed with islands of cells with brightly eosinophilic, granular cytoplasm. |
| Absolute cell counts of macrophages, lymphocytes, and eosinophilic and neutrophilic granulocytes were calculated. |
| There was a moderate amount of lightly eosinophilic cytoplasm, and cytoplasmic borders were ill-defined. |
| Third, combined eosinophilic and neutrophilic airway inflammation may enhance eosinophilic degranulation through neutrophil protease activity. |
| The distribution of these patchy infiltrates can be peripheral, resembling chronic eosinophilic pneumonia. |
