[Ultrastructural characteristics of tubular and tubulovillous adenomas of the large intestine].
Electron microscopic study of adenomas showed absorptive cells (with or without a brush-board), goblet cells, and, less frequently, endocrine cells, and thus organ- and tissue-specific features of normal tissue. There was no relationship between the occurrence of the above cells and the degree of cell dysplasia. However, adenomas showed undifferentiated and moderately-differentiated enterocytes, their level depending on the degree of cell dysplasia. Pronounced dysplasia was often associated with a high level of undifferentiated cells.
