Depending on the types of ISLET CELLS present in the tumors, various hormones can be secreted: GLUCAGON from PANCREATIC ALPHA CELLS; INSULIN from PANCREATIC BETA CELLS; and SOMATOSTATIN from the SOMATOSTATIN-SECRETING CELLS. Most are malignant except the insulin-producing tumors (INSULINOMA).Neck Injuries: General or unspecified injuries to the neck.

It may also occur in sites where glandular or columnar epithelium is normally present. (From Stedman, 25th ed)Femoral Neck Fractures: Fractures of the short, constricted portion of the thigh bone between the femur head and the trochanters.
