Additional findings were severe periportal hepatitis consisting of variable numbers of lymphocytes admixed with fewer heterophils and plasma cells; peribronchiolar
aggregations of macrophages containing intracytoplasmic silica; accumulation of amorphous, basophilic material admixed with colloid within the thyroid follicles (case 1); and mild interstitial lymphoplasmacytic nephritis (case 2).
The distribution of the process appeared to be random, with intra-alveolar hemorrhage seen in subpleural, intralobular, paraseptal, and peribronchiolar
The rise in intraalveolar pressure, in addition to barotrauma caused by vigorous coughing, can cause both alveolar rupture and air dissection in the peribronchiolar
Due to peribronchiolar
fibrosis and scarring, the bronchial lumina are strangulated from the outside, causing stricture of those structures, while the alveolar areas are relatively intact on histopathology.
The intensity of the "infiltrating" eosinophil response was graded on an arbitrary scale of 0-4 (0 = no response; l=mild response, 2 = moderate response; 3 = strong response; 4 = sever response, as judged by the density of leukocytes infiltrating to the peribronchial and peribronchiolar
3]-induced inflammation in perivascular, peribronchiolar
, and terminal bronchial regions in hemotoxylin and eosin (H&E)-stained lung tissue sections from [Il10.
Bronchiolar walls were moderately infiltrated by neutrophils and had multifocal epithelial necrosis and multifocal peribronchiolar
moderate infiltration by macrophages and lymphocytes and few neutrophils and plasmacytes.
The most common early radiographi c abnormalities are bilateral, symmetric, peribronchiolar
, micronodular and interstitial infiltration with a predominance of middle and upper lobe involvement (6) as in miliary tuberculosis.
In MTB haematogenous showers of Mycobacterium tuberculosis bacilli seed mostly the pulmonary interstitium and may secondarily involve the peribronchiolar

Treatment with vidofludimus also significantly reduced peribronchiolar
inflammation, while CYC and MMF failed to achieve any protection of the lung.
In situ hybridization demonstrated monotypic k light-chain expression (Figure 2, G) without [lambda] light-chain expression (Figure 2, H) in peribronchiolar
