Medical lung diseases
The medical lung diseases are a huge topic. Most pathologists have little to do with 'em. They are the domain of respirology. An introduction to lung pathology is in the lung article, along with a general approach. Interstitial lung disease is dealt with in the diffuse lung diseases article.
Infectious pneumonia
Includes:
Asthma
General
- The bread and butter of respirology.
- May be associated with atopy (allergies), medications (e.g. NSAIDs), occupational exposures.[1]
Pathogenesis
- T-cell response TH2 dominant.
Sequence:[2]
- Antigen TH2 lymphocyte -> IgE B-cell -> mast cell IgE Fc -> leukotrienes + other mediators -> bronchospasm, edema, leukocyte recruitment -> airway remodeling.
Gross
- Lung over-inflation.
- Mucous plugs.
- Focal resorption atelectasis,[3] i.e. collapse.
Microscopic
Features:[4]
- Edema.
- Mucous (plugs).
- +/-Smooth muscle hypertrophy.
- +/-Inflammation - especially with eosinophils.
- +/-Charcot-Leyden crystals (formed from eosinophil granules -- breakdown product).
- Sharp edge, diamond shaped, intense pink.
Images:
Notes:
- Leyden in Charcot-Leyden is also seen written as Leiden.
- Pulmonary cytopathology: Curschmann's spirals - spiral-shaped mucous plugs.[5]
Emphysema
General
- Usually due to smoking.
- May be associated with alpha-1 antitrypsin deficiency.
- Often lumped together with chronic bronchitis and called chronic obstructive pulmonary disease (COPD).[6]
Pathologic classification
Based on morphology:[7]
- Centriacinar (centrilobular) emphysema - associated with heavy smoking.
- Panacinar (panlobular) emphysema - associated with alpha-1 antitrypsin deficiency.
- Distal (paraseptal) acinar emphysema - associated with spontaneous pneumothorax.
- Irregular emphysema - usu. insignificant.
- Q. Why does smoking lead to centriacinar emphysema?
- A. The bad stuff from smoking gets enters the acinus at the centre; ergo, this is the location of the most damage.
Gross
- Holes (blebs, bullae), usually upper lung field predominant.
- Lungs may overlap the heart.[8]
Notes:
Microscopic
Features:[8]
- Large alveoli.
- Thin septa (no interstitial thickening).
Image:
