We report a rare case ofrectal neuroendocrine carcinoma(NEC)following sigmoidectomy of sigmoid colon cancer. NEC of the rectum is a rare disease. It has an extremely poor prognosis and a high potential for malignancy with hematogenous and lymph node metastases. A 90-year-old man who had carcinoma ofthe sigmoid colon 2 years ago was found to have rectal NEC based on endoscopy findings. He underwent the Hartmann operation. Histological and immunohistochemical analyses showed NEC. Four months after the surgery, he developed local recurrence with lymph node metastasis. He was not administered chemotherapy because ofhis old age. Although the patient needed strict outpatient care, he remained symptom-free 4 months after the Hartmann operation.
我们报告了1例乙状结肠癌乙状结肠切除术后发生直肠神经内分泌癌（NEC）的罕见病例。直肠NEC是一种罕见疾病。其预后极差，具有通过血行和淋巴结转移的高恶性潜能。一名90岁男性，2年前患有乙状结肠癌，基于内镜检查结果发现患有直肠NEC。他接受了哈特曼手术。组织学和免疫组化分析显示为NEC。术后4个月，他出现局部复发并伴有淋巴结转移。由于他年事已高，未给予化疗。尽管患者需要严格的门诊护理，但哈特曼手术后4个月他仍无症状。
