Unlabelled:
Mucocele of the appendix is a very uncommon disease estimated to be seen in 0.2-0.3% of all appendectomies (0.28% in our series). The term "mucocele" means dilation of the appendix due to mucus, caused either by a benign process or a malignant one (cystadenoma or adenocarcinoma).
Material And Methods:
We present a series of 31 cases (17 females) treated over 18 years and with a mean age of 62 years. The most frequent clinical symptom (14 cases, 45%) was pain in the right iliac fossa of less than 72 h onset which simulates acute appendicitis.
Results:
The histology results showed that it was benign in 21 cases. The appendix was removed in all cases; five by laparoscopy, with caecal resection in 8 cases (1 was a cystadenocarcinoma) and right ileocolectomy in 15 patients (9 malignant).
Conclusion:
Follow up is recommended, not only to monitor the appendicular disease, but also due to the high incidence of synchronic or metachronic tumour processes in other areas.
Insights
Mucocele of the appendix, a rare condition causing appendix dilation, can be benign or malignant. This study reviewed 31 cases, highlighting appendiceal mucocele diagnosis and management.
Area of Science:
- Gastroenterology
- Surgical Pathology
- Oncology
Context:
- Mucocele of the appendix is a rare condition, occurring in 0.2-0.3% of appendectomies.
- It involves appendix dilation due to mucus, potentially stemming from benign or malignant processes like cystadenoma or adenocarcinoma.
- Clinical presentation often mimics acute appendicitis, with right iliac fossa pain being the most frequent symptom.
Purpose:
- To analyze a series of 31 appendiceal mucocele cases treated over 18 years.
- To describe the clinical presentation, histological findings, and surgical management of appendiceal mucoceles.
- To emphasize the importance of follow-up due to potential synchronous or metachronous tumors.
Summary:
- A review of 31 cases (17 female, mean age 62) revealed appendiceal mucocele, with 45% presenting with acute right iliac fossa pain.
- Histology confirmed benign etiology in 21 cases. Surgical interventions included appendectomy, laparoscopic procedures, cecal resection, and right ileocolectomy.
- Malignancy was identified in 9 cases, including one cystadenocarcinoma, underscoring the need for thorough evaluation and management.
Impact:
- Provides insights into the clinical and pathological spectrum of appendiceal mucocele.
- Highlights surgical strategies for managing this uncommon condition.
- Stresses the critical need for long-term surveillance for associated neoplastic processes.
