Pneumonia is inflammation of the lung, which includes infectious and non-infectious etiologies.
It is a subset of the medical lung diseases. This article primarily deals with the infectious pneumonias.
Idiopathic interstitial pneumonias are listed at the bottom; they are dealt with in detail in the diffuse lung diseases article.
Anatomical classification of pneumonia
- Generally, not used by clinicians.
- Use of the terms without qualification is discouraged... as they do not make explicit the etiology.
- Multiple foci of (acute) inflammation involving the bronchi.
- This is the most common form of (infectious) pneumonia.
- Pneumonia that involves a whole lobe.
- Rarely seen in areas where antibiotic treatments are widely available.
Acute infectious pneumonia
Main article: Acute infectious pneumonia
The most common form of pneumonia. It is usually diagnosed clinically.
Chronic infectious pneumonia
- Mycobacterium tuberculosis.
- Atypical mycobacterium, e.g. Mycobacterium avium-intracellulare.
- Histoplasma capsulatum.
- Coccidioides immitis.
- Blastomyces dermatitidis.
- All of the later ones are granulomatous.
Main article: Aspiration pneumonia
Main article: Cytomegalovirus
- Critical illness.
- CMV nuclear changes:
- Large red nucleus with a pale halo.
- Eosinophilic granular cytoplasmic inclusions.
- CMV +ve -- cytoplasmic inclusions, large nucleus.
Diffuse lung diseases
Main article: Diffuse lung disease
- AKA idiopathic interstitial pneumonia.
- Organizing pneumonia.
- Usual interstitial pneumonia.
- Nonspecific interstitial pneumonia.
- Lymphocytic interstitial pneumonia.
- Desquamative interstitial pneumonia.
- Diffuse alveolar damage.
