Abstract
A 63-year-old male was admitted to Hikari City Hospital because of hoarseness and tarry stool on April 1979. Upper GI series showed multiple gastric ulcer on the angulus and on the lower corpus. By endoscopy large shallow ulcer on the angulus and the small multiple ulcers on the lower corpus were found. Blood gas analysis revealed elevated PCO2 and depressed P02. By laryngoscopy, laryngeal carcinoma was diagnosed and after irradiation, laryngectomy was performed successfully. Three months after admission multiple gastric ulcer were healed. Comparing with gastroduodenal ulcer associated with COPD (Chronic Obstructive Pulmonary Disease), etiology of this case is discussed.
