Follicular bronchitis/bronchiolitis is an uncommon type of medical lung disease.
General
- Similar to lymphocytic interstitial pneumonia (LIP).
- Overlaps with LIP.[1]
- Associated with the things seen in LIP;[2] however, associations may be less clear in children.[3]
Gross/radiology
- No distinct nodule or mass.
- Classically: increased reticular marking, i.e. interstitial pattern.
Images: Intersitial pattern - radiographs (ucsf.edu).
Microscopic
Features:[4]
- Peribronchiolar/peribronchial lymphoid nodules with:
- Reactive germinal centres.
- Lack of these should raise suspicion for lymphoma.
- Plasma cells.
- Reactive germinal centres.
- +/-Lymphoid nodules in the interlobular septa.
Notes:
- Lung parenchyma distant from nodule = normal; no lymphocytic infiltrate.
DDx:
- Lymphoma, specifically MALTomas/BALTomas.
- Lymphocytic interstitial pneumonia.
- Nodular lymphoid hyperplasia.
- This is determined in part by radiology; it has nodules radiographically.
