要旨●患者は50歳代,男性.検診の上部消化管X線検査で腫瘍性病変を指摘され,当院を紹介され受診した.上部消化管内視鏡検査により,胃体上部小彎後壁に25mm大のdelleを伴う粘膜下腫瘍(SMT)を認めた.超音波内視鏡検査では,第4層を主座とし,内部は不均一な低エコーを呈し,ドプラーでは病変内に比較的太い血管を描出した.固有筋層由来のGISTを疑い,非穿孔式内視鏡的胃壁内反切除術(NEWS)で一括切除したが病理組織学的所見は胃迷入膵であった.胃迷入膵は一般的には胃前庭部に発生する開口部様の浅い陥凹を伴うSMTの形態を呈するが,胃体部での発生も散見される.局在および内視鏡診断からGISTとの鑑別が困難であった1例を経験したため報告する.
A 5X-year-old male with a gastric submucosal mass was referred to our institution. Esophagogastroduodenoscopy revealed a sessile submucosal lesion with a 25mm central umbilication on the lesser curvature of the upper gastric body. EUS revealed a heterogenetic hypoechoic mass mainly located in the muscular layer, with blood vessels penetrating the mass. Based on contrast-enhanced CT findings, the tumor was heterogeneously stained. We clinically diagnosed the tumor to be GIST, and nonexposed endoscopic wall-inversion surgery was performed. The diagnosis made was histologically heterotopic pancreas in the stomach.
