Figure 2 Pathology and enhanced computed tomography coronal maximum intensity projection of the chest. A: Lung biopsy revealed a background of proliferating fibrous tissue with irregular nests of epithelial cells; B: The short arrow indicates intercellular bridges and the long arrow indicates a keratin-pearl, which are both typical of squamous cell carcinoma [(hematoxylin and eosin staining, original magnifications 100 × (A) and 400 × (B)]; C-E: Enhanced computed tomography coronal maximal projection intensity of the chest showed that the pulmonary artery passed through the cavity and masses.
