A 53-years-old woman suffering intermittent abdominal pain for several years was admitted with bowel obstruction. Examinations showed a small intestinal tumor. Surgery showed a submucosal tumor 90 cm proximal from the terminal ileum. Bowel obstruction was caused by mural thickening due to tumor invasion. We also found enlarged lymph nodes in the mesentery near the tumor. Two submucosal lesions were also found. Histologically, all 3 tumors were carcinoid, and argentaffin-positive. Immunohistochemically, tumor cells were serotonin-positive. Lymph nodes metastasis was also seen. Small-bowel carcinoid tumor usually metastasizes, developing multicentric tumors. According to the literature, 5-year survival in patients with this malignancy in 55∼58%. Our patient remains disease free for 4.5 years after resection. These tumors are reported to keep recur even after 5 years, however, and longer-term postoperative follow-up is necessary for patients with small-bowel carcinoid tumor.
