Vasoactive Intestinal Peptide-producing tumour (VIPoma) is rare. It typically causes the Vernor-Morrison syndrome characterized by watery diarrhoea, hypokalemia and achlorydria/acidosis. We report a case of VIPoma presenting with severe Vernor-Morrison syndrome requiring intensive care and a review of recent English literature from year 2000 till 2010 for this rare disease. Prompt recognition and early diagnosis are crucial to allow early intervention and improve outcome for this rare disease.
