Solitary gland type adenomas and papillomas are rare benign bronchial tree tumors. Alveolar adenomas, though rare, present as nodules and can be challenging during frozen section evaluation.

Area of Science:

  • Pulmonary Medicine
  • Thoracic Oncology
  • Pathology

Background:

  • Benign tumors of the bronchial tree, including solitary gland type adenomas and papillomas, are rare.
  • These tumors, particularly alveolar and papillary adenomas, predominantly occur in the peripheral lung parenchyma.

Observation:

  • Alveolar adenomas and papillary adenomas are infrequently observed, often incidentally diagnosed as solitary pulmonary nodules in adults over 45.
  • While generally recognized by their distinct morphology, alveolar adenomas can pose diagnostic challenges during intraoperative frozen section analysis.

Findings:

  • The study presents two cases: one of pleomorphic adenoma and one of alveolar adenoma.
  • A comprehensive review of existing literature on these rare bronchial tumors is conducted.

Implications:

  • Accurate diagnosis of these rare lung tumors is crucial for appropriate patient management.
  • Understanding the diagnostic nuances, especially for alveolar adenomas in frozen sections, can improve surgical outcomes.
