title: Gastrointestinal stromal tumour and hypoglycemia in a Fjord pony: case report.
abstract: BACKGROUND
  Neoplasia may cause hypoglycemia in different species including the horse, but hypoglycemia has not previously been reported in the horse associated with gastrointestinal stromal tumours.
  
  
  METHODS
  A case of a gastrointestinal stromal tumour in a Fjord pony with severe recurrent hypoglycemia is presented. The mechanism causing the hypoglycemia was not established.
  
  
  CONCLUSIONS
  This case indicates that a gastrointestinal stromal tumour may cause hypoglycemia also in the horse.
