Insulinoma

Insulinoma (lusulinoma) is a pancreatic islet B cell tumor, also known as endogenous hyperinsulinemia. It accounts for 70 to 75% of islet cell tumors. Most of them are benign, with 10-16% being malignant. Insulinoma can occur at any age, but it is more common in young and middle-aged people, and about 74.6% of patients occur between 20 and 59 years of age. There are more men than women, and the ratio of men to women is 1.4 to 2.1.
