title: The small carcinoma of the large bowel.
abstract: Four small carcinomas (3, 6, 10, and 15 mm) of the large intestine have been examined for residual epithelial polyp; none was found. It is felt that these carcinomas arose from colonic mucosa without a preexisting visible epithelial precursor lesion; however, occasional glands having adenomatous change were seen near the edges of the carcinomas.
