Abstract
The diagnosis of neuroendocrine malignant tumor in the small bowel is difficult [J Oncol 2008;2008:212067]. It is usually found intraoperatively during intestinal resection and confirmed by subsequent histological examination. We reported a case of jejunum neoplasm which was misdiagnosed as Crohn’s disease by capsule endoscopy. Capsule endoscopy was stuck in the jejunum stricture and was removed with a snare under double-balloon enteroscopy. The pathology of the biopsy was jejunum small cell malignant carcinoma tending to neuroendocrine malignant tumor. The immunohistochemical result revealed that CD99 and Ki-67 were positive. The patient underwent intestinal resection and the diagnosis of neuroendocrine malignant tumor was confirmed.
