胰岛素瘤(Insulinoma)是发生于胰岛β细胞的一种肿瘤。由于它的细胞也能分泌胰岛素,故又叫功能性β细胞瘤。过去对本病的命名比较混乱,目前,对胰岛腺的内分泌肿瘤,均以其所产生的激素又加上个瘤(oma)字而命名,故称为胰岛素瘤。功能性胰岛β细胞瘤细胞,虽然具有形成、贮藏和释放胰岛素的能力,但与正常不同,它们对正常影响胰岛素释放的控制机制反应失常,可不受约束的释放胰岛素,结果导致低血糖反复发作。这些病人在禁食期间,胰岛
Insulinoma is a tumor that occurs in islet beta cells. Because of its cells can also secrete insulin, it is also called functional beta cell tumor. In the past the name of the disease is more confusing, at present, the endocrine gland of the islet gland, are produced by the hormones plus a tumor (oma) word named, it is called insulinoma. Functional islet β-cell tumor cells, while having the ability to form, store and release insulin, normally do not respond properly to the normal control mechanisms that affect insulin release and release unconstrained insulin, resulting in recurrent episodes of hypoglycaemia. These patients are islets during fasting
