Background There is lack of consensus on the incidence of appendiceal carcinoids in recent times. The influence of number of appendicectomies performed has been postulated to play a role in this. To determine the incidence and clinico-pathological profile of appendiceal carcinoids in a cohort of patients undergoing emergency appendicectomies for clinically suspected acute appendicitis, and exam...

Extrarenal rhabdoid tumors (ERRTs) are extremely rare neoplasms; of these, colorectal ERRTs are the most rare, and only nine cases have been previously described in the English language literature. The current study reports the pathological features of a case of poorly differentiated cecal adenocarcinoma with prominent rhabdoid feature, which was combined with mucinous cystadenoma of the append...

BACKGROUND Mucinous cystadenocarcinoma is the second most common etiology of appendiceal mucocele. We report a relatively rare case of a giant appendiceal mucocele caused by mucinous cystadenocarcinoma, which occupied the entire abdomen of an adult woman. CASE PRESENTATION A 63-year-old woman presented with a chief complaint of abdominal distention. Imaging studies showed a giant cystic mass ...

BACKGROUND Low-grade appendiceal mucinous neoplasms (LAMNs) are cytologically low-grade tumors of the appendix and are a frequent cause of pseudomyxoma peritonei. They can become a diagnostic challenge when they metastasize to the ovaries, where they may mimic primary ovarian mucinous tumors. CASE REPORT We report the case of a patient with very large bilateral ovarian mucinous tumors and a con...

Background and aims: The appendix may be involved in ulcerative colitis (UC) to variable extent. Clinical significance of appendicular involvement is not clear and it has long been considered an innocent bystander. This study prospectively investigated appendiceal histology and its clinical significance in patients with UC. Materials and methods: Colonoscopy was performed in 60 patients and bio...

These supplemental materials provide appendices not included in the main text. Supplemental Appendix D gives derivations for the examples given in Sections 4 and 5. Supplemental Appendix E considers feasible versions of the procedures in Section 3 in the case with unknown error distribution and derives their asymptotic efficiency. Supplemental Appendix F gives some auxiliary results used for re...
