Abstract
Relations between herpes zoster and gastrointestinal lesions were studied in 1989 and 1990. During this period, 25 cases of herpes zoster were observed by upper gastrointestinal endoscopic examinations, because of symptoms of epigastralgia etc. Abnormal endoscopic findings were noted in 10 of these cases. All cases had benign lesions of gastric ulcer and gastric erosion. Of the 25 cases, 12 were studied by colonoscopic examinations, because of complaints of occult blood stool, etc. Among these 12 cases, 2 abnormal endoscopic findings, ulcerative lesion and erosion, were noted. The shallow ulcerative lesions in the stomach and colon were very similar.
