Presentations

Gross processing

As per presentation above.

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]

Lung cancers by relative incidence.

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%
