Cylindric- or columnar- celled carcinoma in the rectumoriginates in the mucous membrane in the tubular glands orthe crypts of Lieberkiihn. The epithelial cells of these structures multiply newly-formed cells vary in size, but are usually largerthan the normal, have single or multiple nuclei, and may bearranged in one or more layers. As a result of this increasedcell-proliferation, the glands become dilated and irregular inshape, the membrana propria disappears, and branching tu-bules, lined with simple or atypic epithelia, arranged in one ors
