Gross processing
In tumor resection:[1]
- Measure the specimen in 3 dimensions.
- Describe any included pleural surface, including color, and any presence of granularity, adhesions, retraction, or tumor.
- (Ink the surgical margin.)
- Serially section the specimen. Describe the cut surface, including color and consistency, and any focal lesions.
- Measure tumor size as a maximum diameter (or 3 dimensions)
- Determine location: Which lobe if applicable, and if it is peripheral, central or hilar.
- Margin length to pleura and hilum/surgical margin.
- Any involvement of major bronchi or blood vessels.
- Any abnormal lymph nodes, including hilar ones if available.
Photograph all tumors.
Gross report
((A. Labeled - ___. The specimen is received fresh for intraoperative consultation and consists of)) a wedge-shaped piece of lung which measures __ cm and has a staple line along one aspect measuring __ cm in length. The stapled surgical margin is inked black. The visceral pleura is mottled tan-pink and slightly puckered in the center. Cut sections show a tan, soft, tumor measuring __ cm in greatest dimension, located __ cm from the visceral pleura and __ cm from the surgical margin. The remaining parenchyma is pink and spongy. (Representative sections are submitted for microscopic examination in __ cassettes.) |
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.[2]
Subsequently distribution of benign tumors and lung cancers, respectively, are as follows:[2]
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
Squamous-cell carcinoma of the lung. Typical squamous-cell carcinoma cells are large with abundant eosinophilic cytoplasm and large, often vesicular, nuclei.[3]
