When a bulging appendiceal orifice is observed during surveillance colonoscopy, the possibility of appendiceal mucocele must be considered. Appendiceal mucocele is a rare group of lesions characterized by mucinous distension of the appendiceal lumen with the dangerous potential to rupture, resulting in the development of pseudomyxoma peritonei. Early recognition and diagnosis of appendiceal mucocele can prevent the dreaded complication of pseudomyxoma peritonei but it requires a high index of suspicion. Patients with inflammatory bowel disease are at increased risk for colorectal neoplasm but neoplasm of the appendix is infrequently reported. We report two of the first cases of appendiceal mucoceles diagnosed in patients with inflammatory bowel disease using endoscopic ultrasound.

An appendiceal mucocele is a rare clinical entity often mimicking that of acute appendicitis in a majority of cases leading to incidental intraoperative findings. Nevertheless, appropriate diagnosis is vital prior to surgery to prevent complications such as pseudomyxoma peritonei. This report details a case of a man in his 70s, who was admitted to the emergency department with right iliac fossa pain with imaging showing wall thickening of the caecum and the ascending colon.

Appendiceal neoplasms are usually asymptomatic or associated with mild, nonspecific symptoms. Due to the rarity of the disease and the lack of specific symptoms, this clinical entity escapes the diagnostic consideration of the gynecologist, when women come in with right iliac fossa pain. A case is presented of a 56-year-old woman with a mass in the right small pelvis, which was preoperatively diagnosed as originating from the ovary.

Low-grade appendiceal mucinous neoplasm (LAMN) is a rare entity identified in ~1% of patients undergoing appendectomy. The presentation often varies, making diagnosis challenging. Timely identification and treatment are critical to prevent rupture, which may lead to pseudomyxoma peritonei.
