title: Ectopic Cushing's syndrome due to a mesenteric neuroendocrine tumour.
abstract: BACKGROUND
  Neuroendocrine tumours (NETs) are tumours that commonly involve the gastrointestinal system. Common primary sites in the gastrointestinal system include the small intestine, appendix, rectum and pancreas. Mesenteric NETs are extremely rare entities and are sparsely reported  in the literature.
  
  
  METHODS
  We report the case of a 62-year-old woman with ectopic Cushing's syndrome due to excessive adrenocorticotropic hormone secretion by a primary mesenteric tumour in the small intestine and its liver metastases.
  
  
  CONCLUSIONS
  Although rare, the mesentery  can be a primary site for NETs. It can cause similar symptoms and require similar treatment options. Tumour resection and debulking are acceptable ways to improve both the survival and symptoms.
