Gastrointestinal stromal tumors (GIST) are the most common mesenchymal tumors of the gastrointestinal tract, mainly localized in the stomach. Most GISTs derive from mutations in tyrosine kinase receptors or platelet-derived growth factor receptor-α. GISTs are rarely associated with paraneoplastic hypoglycemia caused by a non-β-cells tumor. This syndrome, defined non-islet cell tumor hypoglycemia (NICTH), arises from excess tumor production of insulin-like growth factor. We describe the case of a 67-year-old female with severe NICTH secondary to an advanced and metastatic GIST.
