dc.description.abstract | Ultrastructural changes that occurred in chronic active ulcerative colitis and Crohn's disease were investigated and compared to normal as well as to higher grades of dysplasia in adenomas and carcinomas. A greater number of immature absorptive cells, undifferentiated and intermediate cells were seen as compared to normal. One case of Crohn's and two cases of chronic ulcerative colitis including one with coexisting carcinoma showed increased number of vesicles and electron-dense bodies (EDB) in the absorptive cells and increased heterogeneity of mucin droplets in goblet cells and presence of atypical secretory cells (ASC). Higher grades of dysplasia characterised by large numbers of atypical secretory cells were not seen in the present series and provide no relationship between the atypical ultrastructural features and increased risk of malignancy. However, the number of cases investigated is too small and a large series is required to clarify the significance of observations such as increased number of electron-dense bodies and vesicles in the apical cytoplasm and presence of atypical secretory cells. | es |
