Group of nodular infllammatory lesions observed in common variable immunodeficiency (CVID). Approximately 10% of patients with common variable immune deficiency (CVID) have a systemic granulomatous disease with associated interstitial lung disease.
pulmonary lymphoid hyperplasia
- BALT hyperplasia (follicular bronchiolitis)
- bronchiolocentric lymphoid follicles with germinal centers
- lymphoid hyperplasia
- lymphoid follicles with germinal centers with a widespread distribution, often along lymphatic pathways and interlobular septa
- lymphocytic interstitial pneumonia (nodular LIP)
- nodular lymphocytic interstitial pneumonia (nodular LIP)
- LIP is characterized by diffuse interstitial inflammatory infiltrates consisting of mature lymphocytes, plasma cells, and histiocytes.
non-necrotizing granulomatous lung disease
- occasional clusters of epithelioid histiocytes
- loose clusters of epithelioid histiocytes, multinucleated giant cells, and lymphocytes
B-cell mucosa-associated tissue lymphoma (pulmonary marginal zone lymphoma)
