“…[8,9,18] The symptoms of malignant mucocele cases were linked to weight loss, deterioration of general health, and the presence of intra-abdominal masses, whereas benign mucoceles were more related to acute pain in the right iliac fossa. [2] In our study, 61.5% of patients (n=16) exhibited the characteristics of acute appendicitis. Mucinous cystadenocarcinoma was identified in one patient who underwent a right hemicolectomy.…”

“…[1] Appendiceal mucocele is a disease with an incidence estimated at 0.2%-0.3% of all appendectomies performed and 8%-10% of all appendiceal tumors.

[3] Mucocele of the appendix can be categorized in four histological types, including retention cyst, mucosal hyperplasia, mucinous cystadenoma, and mucinous cystadenocarcinoma.…”

Introduction Low-grade appendiceal mucinous neoplasms (LAMN) are semi-malignant tumors of the appendix which are incidentally found in up to 1% of appendectomy specimen. To this day, no valid descriptive analysis on LAMN is available for the German population. Methods Data of LAMN (ICD-10: D37.3) were collected from the population-based cancer registries in Germany, provided by the German Center for Cancer Registry Data (Zentrum für Krebsregisterdaten—ZfKD). Data was anonymized and included gender, age at diagnosis, tumor staging according to the TNM-classification, state of residence, information on the performed therapy, and survival data. Results A total of 612 cases were reported to the ZfKD between 2011 and 2018. A total of 63.07% were female and 36.93% were male. Great inhomogeneity in reporting cases was seen in the federal states of Germany including the fact that some federal states did not report any cases at all. Age distribution showed a mean age of 62.03 years (SD 16.15) at diagnosis. However, data on tumor stage was only available in 24.86% of cases (n = 152). A total of 49.34% of these patients presented with a T4-stage. Likewise, information regarding performed therapy was available in the minority of patients: 269 patients received surgery, 22 did not and for 312 cases no information was available. Twenty-four patients received chemotherapy, 188 did not, and for 400 cases, no information was available. Overall 5-year survival was estimated at 79.52%. Patients below the age of 55 years at time of diagnosis had a significantly higher 5-year survival rate compared to patients above the age of 55 years (85.77% vs. 73.27%). Discussion In this study, we observed an incidence of LAMN in 0.13% of all appendectomy specimen in 2018. It seems likely that not all cases were reported to the ZfKD; therefore, case numbers may be considered underestimated. Age and gender distribution goes in line with international studies with females being predominantly affected. Especially regarding tumor stage and therapy in depth information cannot be provided through the ZfKD-database. This data analysis emphasizes the need for further studies and the need for setting up a specialized registry for this unique tumor entity to develop guidelines for the appropriate treatment and follow-up.

Appendiceal mucocele and peritoneal inclusion cyst mimicking right adnexal masses: a diagnostic challenge in gynecologic practice

et al. 2012

Mucocele of the appendix (MA) is an uncommon disease. Preoperative differential diagnosis of MA and a peritoneal inclusion cyst (PIC) from gynecologic diseases is still a challenge. We herein report a very rare case with MA and PIC. As far as we know, this is the first report of a case having MA and PIC found simultaneously at surgery. A 31-year-old woman complained of lower abdominal pain and high fever. Based on her symptoms and laboratory tests, pelvic inflammatory disease (PID) was considered to be the most probable diagnosis. She underwent antibiotics therapy and her conditions subsided. However, ascites reappeared in a month, and ultrasound and MRI demonstrated a right ovarian cyst and a suspected right hydrosalpinx. Laparotomy revealed large PIC and MA with normal bilateral adnexa. Patients with an adnexal mass or symptoms suggesting PID should be examined carefully considering such conditions in a daily gynecologic practice.
