内容紹介
Summary
The case was a 76-year-old man. He visited our hospital for a positive fecal occult blood test finding at a medical examination. A colonoscopy revealed a macroscopic, 30 mm, type-1 lesion in the cecum. We performed laparoscope-assisted ileocolic resection and D3 dissection, with a diagnosis of cecum cancer. In postoperative histopathological examination, the tumor in the cecum was diagnosed as a well-differentiated tubular adenocarcinoma. In addition, a low-grade appendiceal mucinous neoplasm(LAMN)was observed on the distal side of the appendix. The patient has survived for 9 months after surgery without recurrence. We report this case with a review of the literature.
要旨
症例は76歳,男性。健診で便潜血陽性を指摘され,当院を紹介受診した。下部消化管内視鏡検査で盲腸に30 mm大の肉眼型1型の病変を認めた。盲腸癌の診断で腹腔鏡補助下回盲部切除術,D3郭清を施行した。術後病理組織学検査では,盲腸腫瘍は高分化型管状腺癌の診断であった。また,虫垂遠位側に孤立性の低異型度虫垂粘液性腫瘍(low-grade appendiceal mucinous neoplasm: LAMN)を認めた。術後9か月,無再発生存中である。今回盲腸癌に合併したLAMNの1例を経験したので,若干の文献的考察を加えて報告する。
