Resumen: | Fine structure of normal human parietal peritoneum served as control data for recording changes in the fine structure of the peritoneum of hernial sacs. In these sacs, mesothelial cells retracted, rounded up and some of them eventually separated altogether to give rise to wide open intercellular spaces thus creating unhindered passageways (stomata) between the subserosal connective tissue and the cavity of the sacs. There was a considerable collagen build-up in the subserosal fibrous tissue of hernial sacs. Occurrence of this fibrosis is at variance with an accepted surgical concept which suggests a defect in collagen synthesis as the cause of herniation. In some sacs mesothelial nodules andior peritoneal adhesions were present. Certain cytological changes in the mesothelial cells of hernial sacs showed features in common with cells of malignant tumours in general, and features mimicing malignant mesotheliomas in particular. This is in spite of the fact that thorough gross and light microscopic examination of operative specimens and cytological evaluation of peritoneal effusion failed to reveal any evidence of malignancy. Pathologists should be aware of the consummate ability of mesothelial cells to mimic carcinomas in order to avoid possible diagnostic errors. In this report, an electron micrograph of peritoneal adhesion is being published for the first time in the literature. A syncytium-like firm bond between adjoining mesothelial cells constituted the adhesion which is obviously an irreversible process. |
