53歳女性.上部内視鏡検査にて,7年前に0-IIb型胃小印環細胞癌を,今回は0-IIb型微小胃印環細胞癌を指摘され,幽門側胃切除術と内視鏡的粘膜下層切開剥離術が施行された.病理組織学的にいずれも脈管侵襲(-)の粘膜内病変であった.今回,内視鏡的に指摘困難とされる0-IIb型小・微小印環細胞癌を異時・異所性に同一症例で指摘した.本症例は,これらの病変の再発の可能性と,病変所見を把握した上での術後内視鏡観察の重要性を示した.<br>

A 53-year-old woman was referred to our hospital with a round, discolored lesion measuring 4mm in diameter that was identified as a minute gastric signet ring cell carcinoma. According to the Japanese classification of gastric carcinoma, it was graded as type 0-IIb. Seven years back, the woman had undergone pylorus-side gastrectomy for a small signet ring cell carcinoma, and the present lesion was assumed to result from heterochrony and ectopic recurrence. Endoscopic submucosal dissection was performed for the minute lesion. Clinicopathological findings revealed gastric mucosal cancer without invading lymph vessels or veins, similar to the previous lesion. We therefore report two very rare lesions in the same case. This case report demonstrates the importance of performing regular follow-up gastroduodenoscopy to detect recurrence in patients with these lesions.<br>
