Figure 6 Pathological examination, biopsy from primary lesion. A: Initial biopsy from primary tumor revealed squamous cell carcinoma (× 10). A proliferation of large atypical cells with swollen deep-stained nuclei was observed. A squamous cell carcinoma with a tendency toward keratinization, intercellular bridges, necrosis, and large atypical cells with bizarre nuclei were evident; B: Fourteen months after additional 2 courses of cisplatin plus 5fluorouracil chemotherapy, primary lesion has maintained pathologically negative for cancer (× 20). There is a small infiltration of inflammatory cells, but no obvious evidence of malignant cells.
