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]
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%
Gallery of lung cancers
Lung adenocarcinoma, with lepidic pattern shown, wherein tumors cells cover alveolar walls.
Large cell carcinoma of the lung: neoplastic cells with abundant pale eosinophilic cytoplasm
Squamous-cell carcinoma of the lung. Typical squamous-cell carcinoma cells are large with abundant eosinophilic cytoplasm and large, often vesicular, nuclei.[2]
