난치성 궤양 형태로 발현한 십이지장의 MALT 림프종 1예 = A Case of Duodenal Mucosa-associated Lymphoid Tissue Lymphoma Presenting as a Refractory Ulcer

다국어 초록 (Multilingual Abstract)

Mucosa-associated-lymphoid-tissue (MALT) lymphomas are the most common primary gastrointestinal lymphomas. The stomach is the most common site of involvement in the GI tract. However, MALT lymphoma of the duodenum is rare. The differential diagnosis in a refractory peptic ulcer are current smoking, NSAID use, hypersecretory conditions (gastrinoma and Zollinger-Ellison syndrome), neoplasms, infection (cytomegalovirus, syphilis, and tuberculosis), and Crohn’s disease. Endoscopic findings of duodenal MALT lymphoma are classified as ulcerative, polypoid, and diffuse types. The ulcerative type is the most common type of duodenal MALT lymphoma. Here, we report a case of a 64-year-old male with a history of a refractory duodenal ulcer who was diagnosed with a duodenal MALT lymphoma by immunohistochemical staining.

국문 초록 (Abstract)

MALT (mucosa-associated lymphoid tissue) 림프종은 위장관 림프종에서 가장 호발 하는 림프종으로 십이지장에서는 그 빈도가 매우 낮다. 십이지장 MALT 림프종의 내시경적 소견으로는 궤양형, 융기형, 미만형으로 분류 되는데 그 중 궤양형이 가장 흔한 소견이다. 난치성 궤양의 경우 흡연, 비스테로이드성 진통제 사용, 산의 과다 분비 상태(gastrinoma, Zollinger- Ellison syndrome 등), 종양, 크론병, 감염(결핵, 매독, cytomegalovirus) 등을 고려해야 한다. 64세 남자 환자에서 난치성 궤양 형태로 발현된 십이지장 MALT 림프종 1예를 경험하였기에 문헌 고찰과 함께 이를 보고한다.
