Figures
Figure 1. The upper gastrointestinal endoscopy with thin scope showed a white-colored, movable mass lesion occupying the lower pharynx.
Figure 2. Stenosis was seen at the upper esophagus. The endoscope could not get through the stenosis.
Figure 3. Computed tomography (frontal plane). A large mass occupied the lower pharynx.
Figure 4. Computed tomography (sagittal plane). Marked wall thickness was seen at the upper to middle esophagus. The lesion had protruding parts at the both edges, shown as low-density area, indicating inflammatory change.
Figure 5. Computed tomography (sagittal plane with specific coloring). The border of the bronchus (showed as green area) looks clear and smooth.
Figure 6. Pathological examination of the biopsied specimen showed squamous cell carcinoma of the esophagus (HE stain).
