We experienced a case of nodule aggregating lesion in the appendical orifice. A 74-year-old woman was admitted to our hospital because a cecal tumor was detected colonoscopically and the biopsy of the same lesion was malignant (group V) , following a positive fecal occult blood test. When she was 28 years old, she underwent sterilization, with appendectomy.
Colonoscopic findings showed a nodule aggregating lesion in the appendical orifice. We considered endoscopic mucosal resection (EMR) for this lesion, but it was high risk of perforation and remnant, so we selected laparotomy. We performed partial resection of the ceacum by auto-suture device only one time. She was discharge after 7 days. Histological examination revealed that the tumor was well differentiated tudular adenocarcinoma which limited in the mucosa.
