Glycogenic acanthosis(GA) of the esophagus,is often found in routine endoscopic examination of the upper GI tract but has not drawn much attention. However, there is controversy concerning the nature, clinical significance and prevalence of this candition. An endoscopic study, performed in 1041 patients, showed that the incidence of GA was 32,9%. Its incidence was found to be significantly higher in male than in female(40.0% vs. 22.1%; p<0.0001) and frequency of high grade(II+III) GA was higher in male than in female(58.1% vs. 45.3~%; p<0.0D01). An increasing tendency was observed with respect to age(X 36~343, p~<0,0001). The frequency of GA was higher in smoker than in non-smoker(49.2% vs. 20.8%; p<0.0001). GA did not have a clear relationship with alcohol intake, dietary habit, condiments, and diet temperature. The frequency of GA was higher in the patient with reflux esophagitis than without reflux esophagitis(3.8% vs. 1.7%; p~<0.05). Therefore, age, sex and smoking appear to be risk factors of GA, as in esophageal carcinoma.
