Laryngeal carcinoma is a subset of head and neck pathology.

Normal histology

The normal histology is dependent on the site.[1]

Pathology

Laryngeal squamous cell carcinoma

General

  • 95% of laryngeal carcinomas.[2]

Risk factors:[2]

  1. Smoking.
  2. Alcohol.

Carinoma - subclassification by site

It is generally divided the following way:[3]

 
 
 
 
 
 
 
 
Laryngeal cancer
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Supraglottis
 
 
Glottis
 
 
Subglottis

Features:[4][5]

  • Prevalence - glottis > supraglottis > subglottis.
  • Glottic carcinoma tends to present earlier (as it affects phonation) and, therefore, has a better prognosis.

Microscopic

See squamous cell carcinoma.

  WITH LYMPHOVASCULAR INVASION.

COMMENT:
The presence of invasive squamous cell carcinoma is confirmed by a second pathologist.
