Abstract
The endoscopic detection of 18 early [human] hypopharyngoesophageal carcinomas has allowed the detailed study of the morphological correlation between endoscopy and histology (in 10 cases). Four different endoscopic types of intraepithelial carcinomas were defined; their morphology, mapping and evolution are greatly variable. In high-risk groups (heavy smoking and alcohol consumption, ENT [ear, nose and throat] cancer), the multicentricity of intraepithelial carcinomas (80%) entails a thorough endoscopic screening of the upper digestive tract (mouth, pharynx, esophagus) and of the lower respiratory tract (larynx, trachea and bronchi).
