62歳男性.心窩部痛精査にて上部内視鏡検査を施行され,胃前庭部に全周性3型胃癌を指摘された.病変に対し幽門側胃切除術が施行され,浸潤性微小乳頭癌併存胃癌と診断された.術後,化学療法が施行されたが,多発肝転移にて再発し,診断から3年3カ月で永眠された.他臓器では微小乳頭癌は予後不良,高悪性度を示すまれな組織亜型として知られているが,胃癌での報告はまれと考え文献的考察を加えここに示す.

A 62-year-old man was admitted for the evaluation of epigastric pain. Upper gastrointestinal endoscopy revealed a type 3 circumferential carcinoma in the gastric antrum. Distal gastrectomy was performed, and the lesion was histopathologically diagnosed as gastric cancer with an invasive micropapillary carcinoma component. Chemotherapy was administered after surgery; however, he died with multiple liver metastases after 39 months. Micropapillary carcinoma is a rare, high-grade, malignant histological subtype of gastric cancer that has not been described in detail till date. Here we describe this rare lesion and present a review of the relevant literature.
