Incidentally discovered low-grade appendiceal mucinous neoplasm: a precursor to pseudomyxoma peritonei

Area of Science:

• Gastroenterology
• Surgical Oncology

Background:

• Appendiceal mucoceles (AMs) are rare cystic neoplasms of the appendix.
• While infrequently malignant, AMs pose a risk of rupture.
• Preventing rupture is crucial to avoid pseudomyxoma peritonei.

Observation:

• AMs have a low incidence of underlying malignancy.
• Treatment strategies have evolved towards less invasive approaches.
• Appendectomy is the primary treatment modality for AMs.

Findings:

• AMs can be managed with appendectomy alone when pathology does not indicate malignancy.
• Rupture of AMs is a significant concern due to potential complications.
• Histopathological examination is essential to rule out malignancy.

Implications:

• Less aggressive management for non-malignant AMs reduces patient morbidity.
• Early diagnosis and appropriate surgical intervention are key to successful outcomes.
• Preventing AM rupture safeguards against the development of pseudomyxoma peritonei.
