Symptoms of PNETs can vary widely depending on whether the tumor is functioning (hormone-producing) or non-functioning. Common symptoms include:
- Abdominal pain - Nausea and vomiting - Diarrhea - Hypoglycemia (low blood sugar) - Jaundice (yellowing of the skin and eyes)
Children with functioning PNETs may present with symptoms related to specific hormone overproduction, such as insulinomas causing hypoglycemia or gastrinomas leading to peptic ulcers.
