Non-hyperinsulinemic hypoglycemia in a patient with a gastrointestinal stromal tumor.
One of the authors (JvD) recently reported a case of non-islet cell tumor hypoglycemia caused by the production of "big" IGF-II by a gastrointestinal stromal tumor (GIST). Here, we report a patient with a GIST in whom non-hyperinsulinemic hypoglycemia was not attributable to aberrant tumoral IGF-II processing, but instead was caused by a combination of cachexia, renal and hepatic dysfunction, and tumoral glucose consumption.
