Non-Islet Cell Tumor Hypoglycemia Secondary to a 20 cm Intra-Abdominal Leiomyoma in a Male Patient: A Case Report and Literature Review.

Non-islet cell tumor hypoglycemia (NICTH) is a rare clinical entity associated with large mesenchymal tumors. Its pathogenesis is most commonly mediated by tumor overproduction of "big" insulin-like growth factor-2. Here, we present a 54-year-old male who presented with noninsulin-mediated hypoglycemia and a 20 cm intra-abdominal leiomyoma.
