Pulmonology Flashcards
Disease?
Asthma
smooth muscle hypertrophy, mucus gland proliferation, prominent basement membrane (black arrows)
Disease
Asthma
accumulation of mucus in lumen of bronchus (yellow star), smooth muscle hypertrophy (black arrow)
squamous metaplasia in center area of epithelium
squamous metaplasia of entire epithelium
goblet cell hyperplasia
centriacinar/centrilobar emphysema (most common, associated with smoking)
panacinar emphysema (associated with alpha-1 anti-trypsin genetic insufficiency)
centriacinar/centrilobar emphysema (most common, associated with smoking)
panacinar emphysema (associated with alpha-1 anti-trypsin genetic insufficiency)
Disease?
emphysema (alveolar changes)
Disease?
chronic bronchitis (increased Reid index, >0.5)
Disease?
chronic bronchitis (bronchus shows wall thickened by chronic inflammation)
Disease?
chronic bronchitis (marked goblet cell hyperplasia)
hyperinflated lungs in patient with emphysema
increased lung markings in patient with chronic bronchitis
Disease?
bronchiectasis
Disease?
bronchiectasis (arrows show dilated bronchi)
Disease?
bronchiectasis (dilation of bronchiole with a chronic inflammatory infiltrate in the lumen)
Organism?
C. diphtheriae (gram positive rods)
Organism?
S. pneumoniae (gram positive diplococci)
Organism
Pseudomonas aeruginosa (gram negative rod; pyrocyanin/pyoverdin = conspicuous blue-green pigment)
Pathology?
dense consolidation of lower lobe
Pathology?
prominent vascular congestion of alveolar capillaries
Pathology?
pulmonary edema: alveolar walls contain congested capillaries, plasma from the blood has moved into alveolar spaces
Pathology?
red hepatization: lungs are heavy, red, and airless
