Abstract

Gastric adenocarcinoma may coexist with tumors of other histological types. The synchronous occurrence of gastric adenocarcinoma and gastrointestinal stromal tumor (GIST) has rarely been reported in the literature. It is still not known whether such an association represents an incidental coexistence or indicates a similar pathogenesis in the simultaneous development of tumors of different histological types. Here we report a case of an exoluminal GIST that was confused with a metastatic lymph node in early gastric cancer.

위 선암은 다른 조직학적 분류를 가지는 종양과 동시에 발생하는 경우가 있으며, 유암종, 점막연관림프종, 평활근육종, 위장관 기질종양 등을 동반할 수 있는 것으로 알려져 있다. 이러한 동시 발생하는 종양에 대해서는 드물게 보고하고 있으나 병태생리에 대해서는 아직 확립된 이론이 없어 이에 대한 연구가 필요하다. 저자들은 조기 위암의 병기 결정을 위해 시행한 복부전산단층촬영에서 작은그물막에 전이성 림프절과 감별이 필요한 종양 소견을 보여, 조기 위암에 대한 내시경 점막하 박리술 시행 후 복강경하 종양절제술 결과 관강외 위장관 기질종양으로 진단한 1예를 경험하였기에 문헌고찰과 함께 보고한다.
