Summary
The endoscopic detection of 18 “early” hypopharyngooesophageal carcinomas, has allowed
us to perform a detailed study of the morphological correlation between endoscopy
and histology (in 10 cases).
We have thus defined 4 different endoscopic types of intraepithelial carcinomas; their
morphology, mapping and evolution are greatly variable. In high risk groups (heavy
smoking and alcohol consumption, ENT-cancer) the multicentricity of intraepithelial
carcinomas (80 %) entails a thorough endoscopic screening of the upper digestive tract
(mouth, pharynx, oesophagus) and of the lower respiratory tract (larynx, trachea and
bronchi).
Key words:
Dysplasia - Carcinoma in situ - Early cancer - Oesophagoscopy
