Some squamous lung cancers appear as solid nodules on imaging and some as ground glass nodules.
Lung squamous carcinoma is a pathologic type of lung cancer that originates from bronchial squamous epithelial cells. In some patients, lung squamous carcinoma lesions are composed of solid components and appear as solid nodules in imaging examinations such as chest CT.
However, due to the invasiveness of squamous lung cancer cells, they will infiltrate the surrounding tissues or be accompanied by inflammation, therefore, they may also contain ground-glass component (i.e. cloudy hyperdense shadow on chest CT), which may be manifested as pure ground-glass nodules or mixed ground-glass nodules, and in some squamous lung cancer lesions, there will be necrosis and liquefaction, which will lead to cystic solid nodules and cavities.
The imaging manifestations of squamous lung cancer are various, and the results of imaging examination can only suggest and assist in the diagnosis of the nature and type of lung cancer, and the specific results of pathological examination should be based on the results.
