Appendiceal mucocele is rare but can be associated with colorectal cancer. Careful pathological examination and patient follow-up are crucial due to potential for pseudomyxoma peritonei.
Area of Science:
- Gastroenterology
- Surgical Pathology
- Oncology
Background:
- Appendiceal mucocele is an uncommon condition, accounting for 0.3%-0.7% of appendiceal pathology.
- It presents as a distended appendix filled with mucus.
Purpose of the Study:
- To analyze the clinical, diagnostic, and pathological features of appendiceal mucocele.
- To investigate the association of appendiceal mucocele with colorectal neoplasms and pseudomyxoma peritonei.
Main Methods:
- Retrospective review of 35 cases of appendiceal mucocele diagnosed between 1985 and 2006.
- Analysis of clinical presentation, imaging (ultrasonography and CT scan), surgical procedures, and pathological findings.
Main Results:
- Most patients presented with right iliac fossa pain; some were incidental findings.
- Pathology revealed mucous hyperplasia, simple mucocele, cystadenoma, and cystadenocarcinoma.
- Four cases coexisted with colorectal cancer; one patient developed pseudomyxoma peritonei.
Conclusions:
- Thorough pathological examination is essential to identify perforations that may affect prognosis.
- Long-term follow-up is recommended due to potential association with colorectal neoplasms and risk of pseudomyxoma peritonei.
