Patient | BAL | Bronchiolar wall | Peribronchiolar tissue | Alveolar spaces | Vasculitis |
---|---|---|---|---|---|
1 | Neutrophilic (72%) and eosinophilic (6%) alveolitis | Goblet metaplasia and eosinophilic infiltration of mucosa and submucosa; thickening of the basal lamina | Nodular lymphoid inflammation and scattered non-necrotizing granulomas | No inflammation | No |
2 | Lymphocytic (85%) alveolitis | Goblet metaplasia and eosinophilic infiltration of mucosa and submucosa; thickening of the basal lamina | Nodular lymphoid inflammation with scattered eosinophils | Mild lymphoid interstitial inflammation with scattered eosinophils; mild macrophage accumulation in the alveolar spaces | No |
3 | Eosinophilic (52%) alveolitis | Goblet metaplasia and eosinophilic and lymphocytic infiltration of mucosa and submucosa. A thickening of the basal lamina. In the bronchiolar lumen: accumulation of epithelial cells, eosinophils and mucous. | Lymphocytic and eosinophilic inflammation mainly around small vessels | Mild interstitial inflammation consisting of lymphocytes and scattered eosinophils | No |
