[A Case Report of Appendiceal NET G1 Diagnosed by Histopathological Examination after Appendectomy for Acute Appendicitis].

ABSTRACT

A 36-year-old woman was diagnosed with acute appendicitis after a close examination of her abdominal pain and nausea. Laparoscopic appendectomy was performed, and pathological examination revealed a NET G1. They were localized lesions on the tips and body of the appendix, with no additional resection because the tumor size was less than 2 cm and no risk factors for recurrence and metastasis(vascular invasion, NET G2 or higher, or invasion of the mesentery). The patient was followed up with contrast-enhanced CT every 6 months and has been recurrence-free for 2 years postoperatively.
