다국어 초록 (Multilingual Abstract)

A sixty four year old male visited our Gastroscopy Room on June 7, 1973, for his stomach trouble v'hich persisted in spite cf medical treatment for many years. Upper G.I. Series done on Oct. 1972 sugested duodenal ulcer and repeated examination on April, 1973 ivas unremarkaLle. On filerscopy of the stonach, there ivas a large ov:il sl;ped ulcer, about 2. 5X 2. 5 cm in ;neter, ivith c!ean-cv.t edge and c.!ean v.lier 1>ase covered liy whitish materiai. T;.e surrounding Illucosa ivas slightly hyperemic and smooth. Filierscopic irn;..essioa was benign gastric ulcer and bior;sy w...s done as a routine on the ulcer edge at fovr <lifferent sites. The result of biopsy, ho;vever, ivas reported as caiicer. Patient vas ir,formed to visit our clinic immcdiately but he came in on July 9, 1973 (32 days after the first examination) and repeated fiberscopv vas done for folloiv-up. Surprisingly the ulcer previously seen has disappeared completely and there remained only mini.mal hyperemia without and erosion or unevenness at the site of previous ulcer. This hyperemic area became only slightly depressed while the gastric v ai.l contracted. Biopsy ivas repeated at this site and it again was reported as cancer. Surgery ivas done and the pathology ivas proved to be mucosal carcinoma. Th;s is a case of so-called early,tom=ch ca::cer g + g b type by Japanese c!assification v;hich is thought to be a type that miznics Lenign ulcer and is often ve,y difficult to I-e difIere;:tiated from benign ulcei. In such a case only repented biopsies following its healing proce.s may make the corre:t diagrosis.
