Intestinal metaplasia with argentaffin cells in the uterine cervix.

Three cases showing focal intestinal metaplasia of the endocervical glands are presented. The intestinal-type epithelium contained absorptive cells, goblet cells and argentaffin cells, and resembled that found in intestinal types of mucinous ovarian tumours. Two of the cases were associated with squamous cell carcinoma-in-situ (CIN III), and both of these also showed borderline glandular malignancy.
