Carcinoid tumors of the liver, or neuroendocrine tumors, are a less common group of tumors that fall between benign and malignant. It mostly occurs in the gastrointestinal tract, but the liver can also be the primary organ. Since I was involved in the removal of one case 5 years ago, I looked up the medical records of my hospital and found that it is not very rare, and I have been encountering some of these cases every year since then. These tumors are not highly malignant, and some of them can be benign, but some of them can show the characteristics of malignant tumors, such as metastasis and recurrence. The reason why it is mentioned here today is that surgery is the only effective method and other treatments including interventions have no significant effect. We hope that both doctors and patients will be aware of this kind of disease and will not treat it simply as liver cancer, especially when given interventional treatment (our hospital has encountered more cases in which liver cancer was considered and interventional treatment was taken, and then operated after the actual effect was very unsatisfactory) and delayed.
