점막내 선암을 동반한 과형성 위용종 1예 = A Gastric Hyperplastic Polyp with Intramucosal Adenocarcinoma

다국어 초록 (Multilingual Abstract)

Adenomatous polyps have been well known to be premalignant, but it is still controversial how to treat and follow them up. Up to date, endoscopic resection has been the choice of treatment, particularly exceeding 2 cm, though there is no concensus on the indications for the excision of hyperplastic polyps. The incidence of malignant tissue found in hyperplastic polyps has been reported to be less than 3%, which is considerably lower than the incidence of greater than 6% reported in adenomas. There have been few reports of hyperplastic polyps in which malignant changes developed during endoscopic surveillance. We report a case of hyperplastic gastric polyp with intramucosal, well- differentiated adenocarcinoma with reviewing references.

국문 초록 (Abstract)

과형성 용종의 경우 부분적 선암을 동반하는 경우가 3% 미만으로 낮은 것으로 알려져 있으나 선종성 용종의 경우 6～75%로 다양하게 보고되고 있다. 따라서 선종성 용종은 암의 전구 병변으로 인식되어 일반적으로 용종 절제술의 적응증이 되지만, 과형성 용종은 양성 용종으로 인식되어 자연 경과와 치료 방침에 대해서는 아직까지 정확히 알려진 바가 없다. 저자들은 최근 상부 위장관 출혈로 내원한 환자에서 출혈의 원인 병소로 진단된 0.5×0.5×2.5 cm 크기의 과형성 용종을 절제술로 치료하고 과형성 용종의 점막내에 국한된 선암을 경험하였다. 이에 과형성 용종에 발생한 선암을 문헌고찰과 함께 보고하는 바이다.
