Recurrence of 6mm Rectal Neuroendocrine Tumor, 14 Years after Excision

#1715

Introduction: Rectal neuroendocrine tumours (NET) constitute 25% of all the digestive NET. Predictive factors of distant metastasis are: size greater than 1cm, high proliferative index and muscularis or lymphovascular invasion. In the absence of these criteria, some authors advocate there is no need for long-term follow-up.

Aim(s): Highlight the malignant potential of low grade NETs and importance of follow-up.
