title: [Carcinoid tumor of gastrointestinal tract: about two clinical cases].
abstract: Carcinoid tumors belong to the families of neuroendocrine tumors. The major sites are the gastrointestinal tract 65% and lungs 25%. The small intestine, specifically the ileum, is the most common. These tumors although rare, are more common in tumors of neuroendocrine origin gastro-entero-pancreatic. In both cases we observe the different clinical presentations that may have carcinoid tumor; in case 1 ulceration of the tumor mass causing the elimination of melena, and severe diarrhea caused by neuroendocrine secretion. Case 2 typical course, totally asymptomatic incidental finding.
