title: [The morphogenesis of polyps of the large intestine].
abstract: The proportion of so-called hyperplastic polyps among other colon epithelial tumours remains unclear. Colon polyps are studied in 400 patients: hyperplastic polyps are found in 107, a combination of hyperplastic polyp with tubular adenoma in 143, tubular adenoma in 72, villous adenoma in 41 and tubulovillous adenoma in 37 cases. Hyperplastic structures and formation of adenomatous structures were, as a rule, observed in a polyp tip, this corresponding to the increase of nuclei volume and DNA amount in the tip colonocytes. The determination of karyometric coefficient (the ratio of the colonocyte nuclei volume in the polyp tip to colonocytes in the intact mucosa) is proposed as a quantitative criterion of proliferative and dysplastic processes.
