Nonislet cell tumor hypoglycemia (NICTH) is a rare but serious paraneoplastic syndrome in which a tumor secretes incompletely processed precursors of insulin-like growth factor-II (IGF-II), causing hypoglycemia. Here, we report an exceptional case of NICTH caused by nonfunctioning adrenocortical carcinoma in a 39-year-old male with recurrent hypoglycemia. The patient's serum IGF-II/IGF-I ratio had increased to 27.8. The serum level of the IGF-II/IGF-I ratio was normalized after removal of the tumor, and the hypoglycemic attacks no longer occurred after the operation.
非胰岛细胞瘤性低血糖症(NICTH)是一种罕见但严重的副肿瘤综合征,肿瘤分泌未完全加工的胰岛素样生长因子-II(IGF-II)前体,导致低血糖。在此,我们报告一例由无功能肾上腺皮质癌引起的NICTH罕见病例,患者为一名39岁男性,反复出现低血糖。患者血清IGF-II/IGF-I比值升至27.8。切除肿瘤后,血清IGF-II/IGF-I比值恢复正常,术后低血糖发作不再出现。
