A. Multiple endocrine neoplasia type I
This is a pancreatic neuroendocrine tumor, a neoplasm found in approximately 60 percent of patients with multiple endocrine neoplasia type I (MEN I). Such tumors also occur in 5–15 percent of patients with von Hippel-Lindau syndrome and occasionally in patients with neurofibromatosis type I. They are not a feature of MEN II.
