Islet cell tumors are typically hyperfunctioning endocrine tumors; they secrete hormones and are most commonly located in which region of the pancreas?

• A. Head
• B. Neck
• C. Body and tail
• D. Tail

Answer: (C)

Islet cell tumors, a type of pancreatic neuroendocrine tumor, come from hormone-secreting cells scattered throughout the pancreas. Although the islets are distributed in the gland, the body and tail are the regions where these tumors most commonly arise. This regional pattern matters because recognizing a lesion there helps explain why many hyperfunctioning pancreatic tumors are found in the body or tail rather than the head. On imaging, these tumors tend to be hypervascular, so when evaluating a patient with a suspected endocrine pancreatic tumor, clinicians often scrutinize the body and tail first. Therefore, the most frequent location is the body and tail of the pancreas.
