title: [Intestinal carcinoid tumour: Case report].
abstract: BACKGROUND
  Carcinoid of the small intestine, is a well-differentiated neuroendocrine tumor that rarely presents with clinical signs. This tumour can be associated with other conditions, such as inflammatory bowel disease, presenting a wide range of symptoms. In some cases they have an aggressive and highly symptomatic behaviour; thus, clinical suspicion must be high to make an early diagnosis.
  
  
  METHODS
  A 60 year-old male patient with Crohn's disease and gastrointestinal symptoms attributed to this disease within the last year. He presented with intestinal obstruction initially treated with conservative management with no improvement. Exploratory laparotomy was performed finding a mesenteric tumour that caused the bowel obstruction. Bowel resection with primary anastomosis was performed. The pathology report showed an intestinal carcinoid tumour with lymph node metastases. The patient recovered well, and was discharged without complications to continue medical treatment and follow-up by the Oncology department.
  
  
  CONCLUSIONS
  In almost 42% of the cases, the most common site of carcinoid tumours is the small intestine, and of these, 41% are presented as locoregional disease. Patients with Crohn's disease present a higher incidence. In these cases, the most common presentation is an acute intestinal obstruction (90%). Surgery is usually curative, and follow up is important as the symptoms of Crohn's disease can hide any recurrence.
