Bronchial Cystadenoma

Epidemiology

  • xxx

Physiology

  • Benign mucoepithelial tumor of the lung

Pathology

  • Papillary bronchial cystadenoma:
  • Mucinous bronchial cystadenoma:

Clinical

  • Endobronchial Nodule/Mass (see Obstructive Lung Disease, [[Obstructive Lung Disease]])
    • Diagnosis
      • FOB: usually occurs as sessile or polypoid mass in airway
        • EBB: diagnostic
      • CXR/Chest CT: atelectasis, post-obstructive pneumonia
    • Clinical
      • Wheezing
      • Stridor
      • Cough
      • Post-Obstructive Pneumonia

Treatment

  • Bronchoscopic Removal: fulguration/laser may be used for poor surgical candidates
  • Surgical Excision ( with wide margins): usually recommended
    • Tumors may locally recur if not completely resected
  • XRT: for positive surgical margins/ recurrent disease
    • Used more commonly with salivary gland origin, less experience with airway origin tumors
  • Chemo: palliative (for metastatic disease)
