초록
위 MALT (mucosa associated lymphoid tissue) 림프종은 상부위장관 내시경 검사에서 매우 다양한 소견을 나타낸다. 저등급 위 MALT 림프종의 경우 주위 점막의 요철을 동반한 다발성의 미란과 얕은 궤양 병변이 대부분이지만, 고등급의 위 MALT 림프종은 궤양침윤형이나 종괴형성 병변이 주된 소견이다. 저등급 위 MALT 림프종에서 진행 위암과 같은 내시경 소견을 나타내는 경우는 매우 드물다. 저자들은 진행 위암과 유사한 내시경 소견이었고 위주변 림프절 침윤이 있었던 저등급 위 MALT 림프종 환자에서 H. pylori 제균과 CHOP 항암약물치료를 시행 후 20개월 동안 재발 없이 추적 관찰 중인 1예를 문헌고찰과 함께 보고한다.
Abstract
Gastric MALT lymphoma usually presents with various endoscopic morphologic characteristics. The majority of the endoscopic findings of low-grade gastric MALT lymphoma reveal multiple and superficial erosions or ulceration with mucosal nodularity, but high-grade gastric MALT lymphomas show ulceroinfiltrative and fungating lesion. However, low-grade gastric MALT lymphoma that presents as advanced gastric cancer is very rare. We experienced a case of low-grade gastric MALT lymphoma with perigastric lymph node infiltration; it presented as advanced gastric cancer, and it was treated with H. pylori eradication and CHOP chemotherapy. So we report on this case along with a review of related literatures.
