A. The tumour was mainly composed of abundant spindle cells. The tumour was absent of glands except that one elongated and narrow gland was displayed here after widely sectioned. (HE × 50) B. The tumour cells were gathered and abundant, whereas collagen was relatively rare. (HE × 100) C. Collagen bundles among the tumour cells were rather ample. (HE × 100) D. The tumour cells displayed inconspicuous eosinophilic or amphophilic cytoplasm, and striking and vesicular nuclei with coarse chromatin or obvious nucleoli. Mitoses were easily found. (HE × 400) E. CD10 was strongly and diffusely positive. (MaxVision method ×200) F. EGFR was strongly and diffusely positive. (MaxVision method × 200).
