Airway tumors

[Britney]

The windpipe (trachea), throat (pharynx), and voice box (larynx) can develop tumors that either grow into the structures or press on them, blocking breathing. Tumors from elsewhere in the body may also spread to these areas (metastasize).
Tumors that develop in the trachea are rare. They are often cancerous (malignant) and found at a locally advanced stage (having spread to nearby tissue or lymph nodes).
The most common malignant tracheal tumors include squamous cell carcinoma, adenoid cystic carcinoma, carcinoid tumors, and mucoepidermoid carcinomas.
The most common noncancerous (benign) airway tumor is a squamous papilloma, although other benign conditions can also occur.

The airway can be affected by primary tracheobronchial tumors, primary tumors that are adjacent to and invade or compress the airway, or cancers that metastasize to the airway.
Primary tracheal tumors are rare (0.1/100,000 people). They are often malignant and found at a locally advanced stage.
The most common malignant tracheal tumors include adenoid cystic carcinoma, squamous cell carcinoma, carcinoid, and mucoepidermoid carcinomas.
The most common benign airway tumor is a squamous papilloma (most often related to human papillomavirus), although pleomorphic adenomas and granular cell and benign cartilaginous tumors also occur.
