“…9,12 Less often, an appendiceal adenoma presents as an abdominal mass or as intussusception of the appendix. 9,12,[20][21][22][23][24][25][26][27][28] Approximately half of the cases are discovered in asymptomatic patients, particularly in women who have undergone an appendectomy during gynecologic surgery. Occasional patients with adenomas in the appendix have concomitant colonic adenocarcinoma.…”

“…[1][2][3][4][5][6][7][8][9][10][11] Although widely used, the term mucocele is inherently imprecise and inclusive of both benign and malignant lesions. The purpose of our study was to identify the clinical, diagnostic, and surgical factors that might be associated with malignancy and affect the surgical management of appendiceal mucocele.…”

All cases of primary appendiceal mucoceles (simple mucocele, cystadenoma, cystadenocarcinoma) diagnosed between 1976 and 2000 were reviewed. There were 135 patients, 74 of whom were female. Mean age at diagnosis was 59 years. Mean follow-up was more than 6 years.Interventions: A total of 129 patients underwent surgery, consisting of appendectomy (22 patients), right hemicolectomy (25 patients), or more extensive procedures (82 patients).Main Outcome Measures: Clinical, diagnostic, and surgical variables were statistically compared with post-operative morbidity and mortality and the presence of malignancy. PϽ.05 was considered significant.Results: The presence of symptoms was associated with malignancy (58% vs 15%, PϽ.001), particularly abdominal pain (56% vs 29%, P=.005) and weight loss (77% vs 31%, P=.002). Abdominal mass was also associated with malignancy (86% vs 25%, PϽ.001). Moreover, pseudomyxoma peritonei and mucocele extravasation were associated with malignancy (95% vs 13%, PϽ.001, and 83% vs 15%, PϽ.001, respectively). The lesion size was not associated with malignancy; however, cystadenomas were significantly larger than simple mucoceles (8.1 cm vs 4.1 cm, PϽ.001), and no cystadenoma was less than 2 cm in largest diameter.Conclusions: A number of clinical, diagnostic, and intraoperative findings are associated with malignant mucoceles. All mucoceles greater than 2 cm should be excised to remove premalignant lesions.
