  • Sputum or bronchial brushings are 80 - 90% sensitive for lung carcinoma if examine 5+ sputum samples
  • Fine needle aspirate is superior to bronchoalveolar lavage for diagnosis of pathologic pathology (Mod Pathol 2002;15:1259)
  • False positives: due to misidentification of macrophages or pneumocytes - includes bronchiectasis, fungal infections, infarct, lipoid pneumonia, postradiation changes, viral pneumonia
  • False negatives: often due to sampling (Diagn Cytopathol 2012;40:556); pleural fluid cytology is often falsely negative for small cell carcinoma
  • Also useful for mutation analysis (Acta Cytol 2012;56:661)
