要旨●患者は70歳代,女性.特に自覚症状なく,200X年に検診目的で施行したEGDで異常を指摘され,当センターに紹介され受診となった.胃体部後壁にSMT様の立ち上がりを有する病変を認め,びまん性大細胞型B細胞リンパ腫(DLBCL)の診断にて幽門側胃切除術を施行した.決潰型の胃DLBCLでは進行胃癌との鑑別を要する場合も少なくないため,形態的に類似した胃癌症例を提示しながら鑑別のポイントについて述べる.
A 70s female was referred to our center after she underwent esophagogastroduodenoscopy during a health checkup that revealed an abnormality without any symptoms in 200X. A lesion with SMT-like rise was detected on the posterior wall of the gastric body. Based on distal gastrectomy findings, the patient was diagnosed with diffuse large B cell lymphoma. Since the diagnosis of gastric diffuse large B cell lymphoma of the fungated type often involves its differentiation from advanced gastric cancer, we present a morphologically similar case of gastric cancer and discuss their key differentiating points.
