Low-grade Appendiceal Mucinous Neoplasm: A Rare Case Presentation

Area of Science:

• Gastroenterology
• Surgical Oncology
• Pathology

Background:

• Low-grade appendiceal mucinous neoplasms (LAMNs) are uncommon tumors of the appendix.
• These neoplasms are characterized by mucin production and minimal cytologic atypia.
• Despite their generally benign nature, LAMNs possess malignant potential if they invade beyond the appendiceal wall, potentially causing pseudomyxoma peritonei.

Purpose of the Study:

• To report a case of LAMN in a young adult male.
• To highlight the clinical presentation and diagnostic process for LAMN.
• To emphasize the significance of prompt diagnosis and complete surgical resection.

Main Methods:

• Case report of a 34-year-old male presenting with abdominal pain.
• Diagnosis confirmed via histopathological examination following appendectomy.
• Clinical follow-up to assess patient outcome and disease status.

Main Results:

• The patient was diagnosed with LAMN.
• Following appendectomy, the patient experienced an uneventful recovery.
• The patient remains disease-free during the follow-up period.

Conclusions:

• LAMNs require timely diagnosis and complete surgical excision.
• Surgical intervention is key to preventing the spread and malignant transformation of these appendiceal neoplasms.
• Complete resection ensures favorable outcomes and prevents serious complications such as pseudomyxoma peritonei.
