Mucinous cystadenoma of the appendix is an unusual neoplasm, which represents one of the histological subtypes of mucocele. Giant appendiceal cystadenomas are extremely rare and most commonly presented with palpable abdominal mass, chronic right lower quadrant (RLQ) pain, or could be asymptomatic. We present a 51-year-old female with clinical picture of acute appendicitis and a giant mucinous cystadenoma of the appendix with low grade dysplasia.

“…The term of mucocele is often used as a general macroscopic descriptive term for dilatation of the appendiceal lumen by mucinous secretions (2)(3)(4)(5)(6). MCA is the most common form, accounting for 63% to 84% of mucocele cases (2,4,7).…”

SummaryAlthough intussusception is a common cause of intestinal obstruction in children, intussusception of mucinous cystadenoma (MCA) of the appendix characterized by distension of the lumen due to accumulation of the mucoid substance is rarely reported. Diagnosis of MCA is usually made perioperatively. In these cases, as a general approach, an appendectomy is performed for cystadenoma, and right hemi-colectomy is recommended for cystadenocarcinoma. However, the type of surgical treatment is related to the dimensions and histology of the lesions. A 12-year-old boy was admitted to our clinic with symptoms of a mobile and painful mass in the right upper quadrant of the abdomen. Abdominal ultrasonography showed intussusception as well as a large, cystic and solid structure extending from cecum to transverse colon. Reduction of intussusception and right hemi-colectomy were performed subsequent to laparotomy. Pathologic diagnosis was reported as MCA. Although MCA is seen rarely, it always should be kept in mind in differential diagnosis of intussusception and intra abdominal mass, especially in children with abdominal pain and distension.

Intussusception is a rare cause of adult intestinal obstruction. Clinical manifestations are not specific, which makes a preoperative diagnosis difficult to establish and often causes delay. We report a case of acute intestinal obstruction due to ileocolic intussusception. An emergency laparoscopy was performed revealing an obstructive mass at the ileocecal region resulting from an appendicular tumor. A right hemicolectomy was conducted. The pathologic examination of the resected sample concluded the mass comprised an appendicular mucinous cystoadenoma. We discuss the clinical features, preoperative diagnosis, and surgical strategies of adult intussusception, as well as the uncommon finding of an appendicular mucinous tumor as its causative lesion, with a review of the available literature.Key words: Adult intussusception -Appendiceal mucocele -Intestinal obstruction I ntussusception is the invagination of a proximal segment of bowel (intussusceptum) into the lumen of the adjacent distal segment (intussuscipiens). Pediatric patients account for 95% of all cases of intussusception, in whom it is usually idiopathic or the result of a viral process; whereas adult patients account for only 1% to 5%, and an organic lesion is found in up to 90% of the adult cases. 1,2Acute bowel obstruction due to intussusception is rare in adults and accounts for 0.003% to 0.02% of hospital admissions and for only 1% of all intestinal obstructions.1 Preoperative diagnosis is a real challenge for physicians because of its unspecific and extremely variable presentation and requires a high index of suspicion. Therefore, the initial diagnosis is usually missed or delayed and may only be established during surgery. [3][4][5] We present a very uncommon case of acute intestinal obstruction resulting from an ileocolic intussusception secondary to a mucinous tumor of the appendix and review the literature about this finding as a lead point. Case ReportA 57-year-old female presented to the emergency department with a 2-to 3-month history of intermittent and worsening abdominal pain, great- est in the right lower quadrant, which had increased gradually over the past 3 days. It was associated with dizziness and diarrhea but she denied any history of fever, nausea, vomiting, bloody stools, or weight loss. The patient's medical history included a groin hernia surgery and gastroesophageal reflux on oral treatment.Initial vital signs were within normal limits. Abdominal examination revealed diffuse tenderness on palpation, above all in the right lower quadrant, but without rebound or voluntary guarding. There was no palpable mass, and the auscultation found struggle bowel sounds. Blood tests were normal as was urine analysis.Abdominal X-ray exam was not demonstrative of intestinal obstruction. Computed tomography (CT) of the abdomen and pelvis showed a pathologic mass at the ileocolic region, of cystic appearance with parietal calcifications, with edematous pericolonic fat stranding suggesting of ileocolic intussusception causing an intestinal obstr...
