Insights
A case of low-grade appendiceal mucinous neoplasm (LAMN) required emergency surgery to prevent metastasis. Laparoscopic ileocecal resection successfully treated the impending appendiceal rupture.
Area of Science:
- Gastroenterology
- Surgical Oncology
- Pathology
Background:
- Low-grade appendiceal mucinous neoplasm (LAMN) is a clinically malignant tumor with potential for metastasis.
- Appendiceal neoplasms require careful management to prevent complications like pseudomyxoma peritonei.
Observation:
- A 55-year-old woman presented with right lower quadrant pain and signs of an impending appendiceal rupture.
- Imaging revealed a tense appendiceal mucinous tumor with nodules, raising concern for appendiceal cancer.
Findings:
- Emergency laparoscopic ileocecal resection with lymph node dissection was performed.
- Pathological diagnosis confirmed LAMN without rupture.
Implications:
- Ileocecal resection is indicated when preoperative discrimination of appendiceal cancer is challenging.
- Improved preoperative imaging is crucial for accurate diagnosis and treatment planning of appendiceal neoplasms.
Introduction And Importance:
We report the case of a patient with a low-grade appendiceal mucinous neoplasm (LAMN) who underwent emergency laparoscopic ileocecal resection to avoid the metastatic spread of tumor cells due to an impending rupture.
Case Presentation:
A 55-year-old woman presented to our hospital with pain in the right lower quadrant of the abdomen. Computed tomography revealed a markedly tense appendiceal mucinous tumor with surrounding inflammation, and laboratory test results showed elevated serum C-reactive protein (7.47 mg/dL), indicating impending rupture of the appendix. Magnetic resonance imaging revealed nodules inside the appendix, suggesting the possibility of appendiceal cancer. We performed emergency laparoscopic ileocecal resection with regional lymph node dissection. The tumor was pathologically diagnosed as a LAMN without rupture.
Clinical Discussion:
LAMN is classified as a clinically malignant tumor because it can cause pseudomyxoma peritonei due to perforation or the presence of residual tissue. Although an appendectomy would be appropriate for LAMN if the tumor margin is secured, ileocecal resection with lymph node dissection is necessary when preoperative discrimination of appendiceal cancer is impossible.
Conclusion:
Further studies of preoperative imaging for appropriate differential diagnosis were necessary.
