 A 63-year-old man was admitted to our hospital with complaints of bloody stool and anal prolapse. Colonofiberscopic examination revealed a subpedunculated tumor in the lower rectum which was removed endoscopically. Histologically, the removed tumor showed an endocrine cell carcinoma with massive submucosal invasion, the cut margin of which was suspected of having been invaded by the cancer. A colonic J shaped pouch-anal anastomosis following low anterior resection with dissection of D3 lymph nodes was carried out. Histologically, the resected specimen showed no residual cancer in the rectum, but there were cancer metastases to several regional lymph nodes. Two years and two months after the operation, the patient died of metastatic endocrine cell carcinoma to the brain, skin and mediastinum. A clinical case of endocrine cell carcinoma with poor prognosis was reported. In addition, immunohistochemical and molecular biological characteristics of the tumor are discussed in this paper.
