pulmonary nodular lymphoid hyperplasia
PNLH, pulmonary pseudolymphoma
Synopsis
expansive and circumscribed nodular lymphoid aggregations along the course of bronchovascular bundles
sharp demarcation from normal parenchyma
follicular lymphoid hyeprplasia
interfollicular lymphoplasmocytosis
extension along lobular septa and in interalveolar septa
no destructive lymphoepithelial lesions
no Dutcher bodies (eosinophilic intranuclear deposits of immunoglobulin)
no follicular colonization by atypical lymphocytes
Associations
dysimmunity - autoimmune disorders
AIDS
Differential diagnosis
simple BALT hyperplasia (follicular bronchiolitis)
lymphoid interstitial pneumonia (LIP)
