Abstract
Morphological features and mucin secretion patterns were investigated in the colonic mucosa adjacent to or overlying mesenchymal or primary epithelial neoplasias, other than adenomas and adenocarcinomas. The material included 15 cases of non-adenocarcinoma tumors examined during 1978-1981. Increased sialomucins and morphological features similar to those described in the so-called transitional mucosa adjacent to primary colorectal adenocarcinomas were observed in only 2 cases. Previous studies have demonstrated transitional profiles in 98% of adenocarcinomas.
