High power view of microscopic photograph of the tumor. A. Bland glands are lined by mucin-rich columnar cells with basal nuclei (hematoxylin and eosin, X400). B. More complicated glands are lined by more atypical nuclei with prominent nucleoli (hematoxylin and eosin, X400). C. Very benign looking glands are present within muscle (hematoxylin and eosin, X400). D. Metastatic tumor glands within lymph node show insignificant cellular atypia (hematoxylin and eosin, X400).
