内容紹介
Summary
A 67-year-old woman with anemia was referred to us for further study. A colonoscopy exhibited multiple tumors(tub1)in the transverse and sigmoid colon(two regions)and rectum. Contrast-enhanced CT revealed no apparent distant and lymph node metastases. Thus, subtotal colectomy with D3 lymph node dissection was performed. Pathologically, the tumor was diagnosed as pStage Ⅱ and pStage 0. After surgery, the patient had no recurrence for 8 months. We herein report a rare case of four synchronous colorectal carcinomas that were successfully treated.
要旨
症例は67歳,女性。貧血精査の下部消化管内視鏡検査で横行結腸(2型),S状結腸(2型,0-Isp)および直腸S状部(0-Ip)に4腫瘍性病変を認めた。全病変がtub1と診断され,大腸亜全摘術(D3郭清)が施行された。病理にてpT3N0M0,pStage Ⅱ(2病変),pTisN0M0,pStage 0(2病変)の同時性4多発大腸癌の診断となった。4個以上の同時性多発大腸癌は比較的まれなため,文献的考察を含めて報告する。
