bronchial benign epithelial tumors

Benign epithelial tumors of the tracheobronchial system

Benign epithelial tumors of the tracheobronchial system and the lungs are exceedingly rare.

These entities encompass bronchial squamous papilloma and bronchial glandular papilloma (as well as their mixed forms) and bronchial adenomas (alveolar adenoma , papillary adenoma , salivary gland-like pleomorphic adenoma and mucinous adenoma and mucinous cystadenoma ).

These tumors are considered to be biologically benign neoplasms; however, they can pose considerable diagnostic difficulties, especially during frozen section evaluation, as they can mimic malignant tumors and in particular they can resemble well differentiated papillary adenocarcinomas.
