#139 Association of carcinoid with noncarcinoid neoplasms
Introduction: Carcinoid tumors have a complex disease spectrum. Most have a benign clinical course, but some are aggressive, with invasive growth, metastasis and short survival. In carcinoid tumors, more than 20% are associated with noncarcinoid neoplasms. When the second tumor is a more malignant lesion, the prognosis usually is correlated more closely with the noncarcinoid malignant neoplasm.

Introduction: Rectal neuroendocrine tumours (NET) constitute 25% of all the digestive NET.
