Carcinoid tumors are neoplasms that include a heterogeneous group of lesions and slow growth. Most of them appear in the respiratory and digestive tract, in appendix, small intestine and rectum in 90% of cases. The right presentation is often treatable and curable and metastases are associated with tumor size, being smaller than 1 cm lesions with low probability of metastasis and greater than 1 cm often give metastases. Carcinoid tumors except the rectum, can produce a variety of endocrine substances whose clinical manifestation is the carcinoid syndrome. The preferred treatment is surgery and in cases of small lesions, endoscopic resection is usually sufficient if not beyond the submucosa and no atypia. We report a male patient of 63 years, peptic symptoms and altered bowel habit, as assessed by rectal polyp findings, the histology reported carcinoid tumor of 0.8 cm so that practical mucosal resection. A year later endoscopic control evidenced rectal carcinoid reinjury high to 5cm below the previous injury, which was resected endoscopically with findings of invasion to the submucosa, there was no evidence to USE carcinoid lesion or lymphadenopathy. He referred to surgery for surgical treatment, left colectomy was performed without histologic evidence of tumor in the surgical specimen.
