polyposis coli  any of several types of polyposis found in the colon.

familial polyposis  , familial adenomatous polyposisFAP  a hereditary condition of multiple adenomatous polyps, lining the intestinal mucosa, especially in the colon; extracolonic manifestations may also be present. Such polyps are first seen around puberty, and nearly all persons who will get them have them by age 35. When this condition appears, the patient will eventually need a colectomy, because colon cancer is inevitable. It occurs as part of several different conditions, including Gardner, Peutz-Jeghers, Canada-Cronkhite, and Turcot syndromes.
