title: [Appendiceal neuroendocrine tumor with lymph node metastasis in a teenager].
abstract: Neuroendocrine tumor (NET) is a cancer-like tumor that occurs mostly in the gastrointestinal system. Within the gastrointestinal tract, NET most commonly occurs in the rectum whereas appendix is very rarely involved. In most cases of appendiceal NET, it is found at a relatively early stage compared to other NETs because appendiceal NET frequently presents with acute appendicitis because appendiceal NET frequently presents with acute appendicitis even when the size is smaller than 1 cm. Therefore, it is very rare for lymph node metastasis to occur in a young adult. Herein, we report a rare case of grade 1 appendiceal NET with lymph node metastasis which developed in a teenage male.
