Week 6 Flashcards

1
Q

Histologically, what differentiates a bronchus from a bronchiole?

A
  • Bronchus has cartilage chips, bronchiole does not
  • Bronchus has goblet cells, bronchiole does not
  • Bronchus has no smooth muscle, bronchiole does

Q

Diffuse Alveolar Damage definition

A
  • the pathologic sequence of events that follows severe [acute lung injury] caused by any one of a variety of toxic insults.
  • Typically occurs in the context of acute respiratory distress syndrome

Q

Characteristics of organizing DAD

A
  • Alveolar collapse
    • Due to epithelial necrosis –> type 2 pneumocytes die –> decreased surfactant
  • pneumocyte hyperplasia
    • In an attempt to repair the damage
  • fibrosis

77
Q

Children pulm stuff that is different from adults

A
  1. Increased respiratory rate

100
Q

ABPA

A
  • Allergic bronchopulmonary aspergillosis

A

mucoid impaction of bronchi with allergic mucin

102
Q

Usual Interstitial Pneumonia characteristic path findings

A
  • Microscoping honeycomb change
    • Bronchioles embedded in scar - looks like cysts embedded in scar tissue
    • scar tissue is pink due to collagen deposition
  • Fibroblastic foci
  • Normal lung right next to fibrotic lung and the fibrotic lung will eventually advance/overtake the normal lung
103
Q

Usual interstitial pneumonia

A
  • Restrictive lung disease
  • Chronic interstitial pneumonia
  • See fibrosis of tissue b/w alveoli = fibrosis of alveolar septa = “patchwork” fibrosis
  • You’ll see normal lung next to fibrotic lung next to fibroblastic foci (the beginning of scar formation)
104
Q

“patchwork” fibrosis of UIP

A
105
Q

Microscopic honeycomb change

A
  • UIP finding
106
Q

Temporal heterogeneity

Q

Radiologic findings of UIP

A
  • Traction bronchiectasis
  • honeycombing
108
Q

Is UIP a clinical or histologic diagnosis?

A

109
Q

What are some common clinical diseases associated with UIP?

A
  • Rheumatoid arthritis
  • Asbestosis
  • Chronic drug toxicity
  • Idiopathic pulmonary fibrosis
110
Q

How is a diagnosis of idiopathic pulmonary fibrosis made?

A
  • Histologically you see UIP
  • Then IPF is a diagnosis of exclusion…ex: if they have rheumatoid arthritis and histologic findings of UIP, they do NOT have IPF.
  • If you rule out every other possibility that can cause UIP, THEN you have a diagnosis of IPF
