전소장과 대장 전체에서 발생한 원발성 위장관 림프종 1예

Primary gastrointestinal lymphoma which is primarily confined to gastrointestinal tract without evidence of systemic involvement is a relatively rare disease. Non-Hodgkin's lymphoma has a tendency to involve extranodal areas as its primary site and the gastrointestinal tract is the most commonly involved extranodal site. Many cases of primary gastrointestinal lymphoma have been reported mostly of gastric origin followed by small howel, ileocecal portion and colon; however, the concurrent lymphoma of colon and small bowel is very rare in reported cases. This article is about a case of 55-year old male who was diagnosed as primary concurrent malignant lymphoma of the entire small bowel and colon. The colonoscopic finding revealed smootb pink-red colored multiple polypoid masses and ulcerations in the total colon. We suspected lymphoma by endoscopic punch biopsy, thereafter laparatomy was performed. Multiple subserosal nodules were scattered from Treitzs ligament to rectum, and mesenteric lymph node enlargement was also observed. As a result malignant lymphoma was confirmed pathohistologically. We report this case with a review of the related literature. (Korean J Gastroenterol 1995;27:581 - 587)
