Histological study of the rectal tumor. (a) Hematoxylin-eosin staining of the rectal tumor. Hematoxylin-eosin staining showed a moderately differentiated adenocarcinoma in the rectal tumor. The mucosa was not affected by the tumor, thus indicating that this tumor did not originate from the rectal mucosa. (b) CK7 staining of the rectal tumor. The rectal tumor was strongly positive for cytokeratin (CK) 7, whereas the normal mucosa was negative for CK7. (c) CK20 staining of the rectal tumor. The rectal tumor was negative for CK20, whereas the normal mucosa was positive for CK20.
