Papillomas of the tracheobronchial tree with malignant degeneration
Abstract:
Papillomas are rare tumors of the respiratory tract, which are usually considered benign. We studied a male patient with adult onset of squamous papillomatosis involving both the trachea and the bronchi, with malignant degeneration. When we obtained specimens bronchoscopically, only the bronchial lesions showed carcinomatous changes. Thoracotomy demonstrated carcinoma in the tracheal lesion as well. We conclude that transbronchoscopic biopsy may be inadequate in the evaluation of papillomatosis.

Tumor Progression
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
Trachea
Anatomical Features:
Location: About half of the trachea is situated in the neck, anterior to the esophagus, and extends from the larynx (at the level of the...
The Bronchial Tree
The trachea, commonly known as the windpipe, is a tube that connects the larynx (voice box) to the bronchi. At a point called the carina, it bifurcates into two primary bronchi. The right primary bronchus is wider, shorter, and more vertical than the left primary...
