Résumé

Les auteurs ont étudié en microscopie électronique à balayage des échantillons de muqueuse colique normale, des adénomes et des polypes hyperplasiques ainsi que des spécimens de la muqueuse adjacente à ces différents polypes. Les informations stéréomorphologiques obtenues au niveau de ces différents échantillons sont en accord avec les hypothèses histogénétiques qui opposent adénomes et polypes hyperplasiques.

A scanning electron microscopy study of normal colonic mucosa, adenomas and metaplastic polyps

Summary

The authors studied in scanning electron microscopy 9 normal colonic mucosa samples, 25 adenomas, 10 metaplastic polyps and specimens of the adjacent mucosa. The stereomorphological data substantiate the histogenetic hypotheses which oppose adenomas to metaplastic polyps.

Aspectos de la mucosa colonica normal y de los polipos adenomatoses e hiperplasicos em microscopia electronica de barrido

Resumen

Los autores han estudiado muestras de mucosa del colon normal, de adenomas y de pólipos hiperplasicos por medio de la técnica de microscopia electronica de barrido, asi como especímenes de la mucosa de vecindad de los diferentes pólipos. Las informaciones estereomorfológicas obtenidas en esas variadas muestras está de acuerdo con las hipotesis histogenéticas que oponen los adenomas a los pólipos hiperplásicos.
