要旨 患者は57歳,男性.検診で便潜血陽性を指摘され,精査目的に当院を受診した.大腸内視鏡検査で直腸に粘膜下腫瘍様の隆起性病変を認めた.表面に浅い陥凹を有し,陥凹内に粘液開口部と思われる小さな結節状隆起を複数認めた.粘膜面に明らかな上皮性腫瘍成分を指摘しえなかったが,開口部からの生検では粘液癌が強く疑われた.直腸癌,Rb,Type 5,MP,N0H0P0M0,cStage Iの診断のもと,超低位前方切除術と所属リンパ節郭清(D2)が行われた.組織学的には粘膜下層~固有筋層にかけて多数の粘液結節が形成され,粘液内に不整な腺管構造をとる腫瘍細胞が浮遊し,高分化型粘液癌の所見であった.
A 57-year-old male revealed a sub-mucosal tumor like mass with a reddened depressed lesion in the rectum. Although atypical glands were not pointed out in the mucosal surface macroscopically, some small prominences with excreting mucus were seen in the depressed lesion. Biopsy specimens of this prominent lesion revealed mucinous adenocarcinoma. Super-low anterior resection and lymph node dissection(D2)were performed. In the histological findings, a lot of mucinous nodules were seen in the sub-mucosal and muscle layer. Atypical glands were floating in the mucinous nodules.
