  • • Bronchial gland adenomas constitute 5% of all lung cancer

    • -Misnomer since vast majority actually malignant

    • Carcinoid lung tumors constitute 85% of bronchial adenomas

    • -Classified as typical or atypical

      -Derived from Kulchitsky cells

      -Located in central, proximal airways

      -Slow growing, can metastasize widely, rarely cause carcinoid syndrome

    • Adenoid cystic carcinoma (cylindromas)

    • -Locally aggressive, metastasis involve lung

      -Slow growing, amenable to resection

    • Mucoepidermoid cancer

    • -Rare tumors; mucus secreting cells and squamous cells present

      -Less aggressive

    • Mucous gland adenoma: Truly benign

Imaging Findings

  • • Chest film

    • Chest CT scan

  • • May present as a solitary pulmonary nodule, and require work-up as such

    • Carcinoid syndrome rare with pulmonary tumors

  • • Chest film

    • Chest CT

    Bronchoscopy: Biopsy for tissue diagnosis; beware of bleeding


  • Surgery primary treatment: Lobectomy or sleeve

    Adenoid cystic carcinomas: Requires generous margins and frozen section exam at surgery

    • Up to 8 cm of trachea can be removed with primary anastomosis


  • • Chemotherapy indicated only for atypical carcinoid


  • • Very good, in general

    • Lymph node and distant metastasis portend poor prognosis
