What's new in benign lung tumours?

Area of Science:

• Pulmonary Pathology
• Oncology
• Genetics

Background:

• Lung cancer is common, but benign pulmonary neoplasms are rare.
• Accurate diagnosis of benign lung tumors is essential to avoid misclassification with malignant mimics.
• Recent advances have illuminated the genetics of benign pulmonary neoplasms.

Purpose of the Study:

• To review common benign lung tumors.
• To discuss their classification, differential diagnosis, and genetic drivers.
• To aid pathologists in distinguishing benign from malignant lung lesions.

Main Methods:

• Literature review of benign pulmonary neoplasms.
• Analysis of diagnostic criteria for common benign lung tumors.
• Summary of current genetic findings in benign lung neoplasms.

Main Results:

• Detailed review of pulmonary adenomas, bronchial papillomas, and benign mesenchymal tumors.
• Discussion of key morphological features and differential diagnoses.
• Overview of identified genetic drivers in these rare tumors.

Conclusions:

• Pathologists must be familiar with benign lung tumor characteristics.
• Understanding genetic drivers enhances diagnostic accuracy.
• This review provides a comprehensive resource for benign pulmonary neoplasm diagnosis.
