“…Mucocele appendix is indicated by a mount-like elevation of the appendix orifice (volcano sign) and yellowish mucus discharge. [ 17 , 18 ] Due to the mass effect of a large mucocele, barium contrast examination may reveal indentation or lateral displacement of the caecum. [ 19 ]…”

Appendiceal mucocele is an appendicular dilatation secondary to the intraluminal accumulation of mucous material. Adequate pre-operative diagnosis and surgical resection remains the standard management. Here, we present three cases of appendiceal mucocele. In the first case, a 60-year-old female presented with signs and symptoms of acute appendicitis and was admitted and operated. An inflamed distended globular cystic mass of appendix measuring 10 × 6 × 4 cm with a wide base was found and the patient underwent right hemicolectomy. In the second case, a 30-year-old male with symptoms and signs of acute appendicitis was admitted to the emergency department. An open surgery was performed and a distended, tense, and inflamed appendix without perforation of size 6 × 1 × 1 cm was discovered and removed. The diagnosis of mucocele appendix was suspected and confirmed by postoperative dissection of the specimen and histopathology. In the third case, a 25-year-old female patient was subjected to diagnostic laparoscopy in view of non-specific pain abdomen. A diagnosis of mucocele of appendix was made intraoperatively and removed using a specimen bag. Appendiceal mucocele with acute presentation is a rare pathology that clinically resembles acute appendicitis. Preoperative detailed investigations to reach a definitive diagnosis are critical for adequate surgical resection and overall outcome.

“…An inappropriate appendectomy can leave a long-segment stump, which can cause stump appendicitis [ 1 , 2 ]. More rarely, there have been several reports on obstructive mucus retention in the lumen of the remnant appendix, forming appendiceal mucinous lesions [ 3 – 5 ]. As described in these reports, residual appendiceal tumors are most commonly derived from an inappropriately left appendiceal stump.…”

Background Neoplasms derived from remnant appendix are rarely described, with most cases arising from the appendiceal “stump”. Here, we present two surgical cases of appendiceal neoplasms derived from appendiceal “tip” remnants. Case presentation The first patient was a 71-year-old man who had undergone laparoscopic appendectomy for acute appendicitis 12 years prior. During appendectomy, the appendiceal root was ligated, but the appendix was not completely removed due to severe inflammation. At the most recent presentation, computed tomography (CT) was performed to examine choledocholithiasis, which incidentally revealed a cystic lesion of approximately 90 mm adjacent to the cecum. A retrospective review revealed that the cystic lesion had increased in size over time, and laparoscopic ileocecal resection was performed. Pathology revealed no continuity from the appendiceal orifice to the cyst, and a diagnosis of low-grade appendiceal mucinous neoplasm (LAMN) was made from the appendiceal tip remnant. The patient was discharged without complications. The second patient was a 65-year-old man who had undergone surgery for peritonitis due to severe appendicitis 21 years prior. During this operation, the appendix could not be clearly identified due to severe inflammation; consequently, cecal resection was performed. He was referred to our department with a chief complaint of general fatigue and loss of appetite and a cystic lesion of approximately 85 mm close to the cecum that had increased over time. CT showed irregular wall thickening, and malignancy could not be ruled out; therefore, laparoscopic ileocecal resection with D3 lymph node dissection was performed. The pathological diagnosis revealed mucinous adenocarcinoma (TXN0M0) arising from the remnant appendiceal tip. The patient is undergoing follow-up without postoperative adjuvant chemotherapy, with no evidence of pseudomyxoma peritonei or cancer recurrence for 32 months postoperatively. Conclusions If appendicitis-associated inflammation is sufficiently severe that accurate identification of the appendix is difficult, it may remain on the apical side of the appendix, even if the root of the appendix is ligated and removed. If the appendectomy is terminated incompletely, it is necessary to check for the presence of a residual appendix postoperatively and provide appropriate follow-up.

Mucocele of the appendix is the accumulation of mucoid material in the appendiceal lumen. Although the terminology is imprecise, as it does not differentiate between the benign and malignant nature of the condition, preoperative recognition is imperative as spillage of the mucus during surgical handling can result in grave complications like pseudomyxoma peritonei. Mucocele developing in a stump of the appendix, i.e., a remnant of appendiceal tissue after surgical removal of an inflamed organ, is an extremely uncommon phenomenon, as not many cases are reported in the literature. In this review, all cases reported in English literature are discussed.
