Gross processing
In tumor resection and autopsy:
- Measure tumor size
- Determine location: Which lobe, and if it is peripheral, central or hilar.
- Margin length to pleura and hilum.
- Any involvement of major bronchi or blood vessels.
- Any abnormal hilar lymph nodes.
Microscopic evaluation
Medical imaging provides a major clue as to whether a lung tumor is benign or malignant, where lesions smaller than 2 cm are likely to be benign, whereas lesions larger than 2 cm are malignant (that is, lung cancer) in 85% of cases.[1]
Subsequently distribution of benign tumors and lung cancers, respectively, are as follows:[1]
Benign lung tumors:
- Hamartomas - 76%
- Benign fibrous mesothelioma/solitary fibrous tumor (SFT) - 12.3%
- Inflammatory pseudotumor (IPT) - 5.4%
- Lipoma - 1.5%
- Leiomyoma - 1.5%
- Other - 3.3%
