Incidental Appendiceal Mucinous Neoplasm Found During Appendectomy in a 15-Year-Old Patient: A Case Report

Year: 2024

Type: article

Abstract: Appendiceal mucinous neoplasms (AMNs) are rare gastrointestinal tumors, often underdiagnosed due to their variable presentation. Low-grade appendiceal mucinous neoplasms (LAMNs) are particularly significant because of their association with pseudomyxoma peritonei (PMP), a condition that increases the risk of abdominal recurrence. This report presents the case of a 15-year-old female with no prior medical history who developed nonspecific abdominal symptoms. Imaging revealed features consistent with appendicitis, leading to a laparoscopic appendectomy. Histopathological analysis confirmed a low-grade mucinous neoplasm confined to the appendix, with no perforation and clear surgical margins. The case underscores the importance of timely surgical intervention and accurate histopathological evaluation, as early diagnosis and appropriate management are crucial for preventing complications such as pseudomyxoma peritonei. This is particularly relevant in younger patients, where the early onset of such tumors is atypical. The rarity of appendiceal tumors and the need for precise surgical and pathological management are critical to improving patient outcomes and reducing the risk of recurrence.
