| pubmed-article:4052956 | pubmed:abstractText | A case of carcinoma in situ of the flat, nonpolypoid mucosa of the large intestine in a 32-year-old man is reported. This case is of unusual importance because it was detected by endoscopy and was effectively managed; it sheds further light into the histogenesis of large intestinal carcinomas; and it points to alternate strategies for early detection and prevention of large intestinal carcinomas. | lld:pubmed |
