Bronchial adenoma

  • Definition

    A bronchial adenoma is a glandular tumor in the trachea or large bronchi (the large airways of the lung) that usually causes obstruction of the airway. Although the term bronchial adenoma classically refers to a benign tumor of the airway -- also known as a mucous gland adenoma -- it is often misapplied to malignant tumors such as carcinomas and carcinoids of the airways.


    Alternative Names

    Bronchial gland tumors; Mucous gland adenoma; Bronchial carcinoid tumors; Adenocarcinoma of the bronchus; Cancer - bronchial adenoma


    Causes, incidence, and risk factors

    These tumors grow slowly and rarely metastasize (spread). The cause is unknown. There is a tendency of this type of tumor to cause bleeding or obstruction of a lung or lung lobe.
