“…The pathophysiology of AI is not fully established, but the main appendicular alteration that has been associated with it is the presence of a mass at that level. It is considered that this pathology presents alteration of peristalsis and, in addition to the association with multiple inflammatory conditions and diseases such as the presence of parasites, foreign bodies, Crohn's disease, lymphoid hyperplasia, endometriosis, mucocele, and neoplasia as in this case [10] .…”

“…When the cecal appendix is involved as the main point of intussusception, the clinical presentation may mimic acute appendicitis [10] . However, there are situations in which patients may be asymptomatic or present symptoms compatible with intussusception such as abdominal pain and vomiting for several, diarrhea, constipation, or melena, similarly to our case [11] .…”

“…Abdominal CT has been considered the main diagnostic tool for an intussusception [8] , [9] , [10] . However, it is considered that in some cases distinguishing between the different anatomical features of the main mass is not easy due to poor discrimination of the edematous bowel wall [9] .…”

“…In adult patients, intussusception lead points are typically pathological in 90 % of cases, 65 % of which are neoplastic in nature [12] . Although there are no macroscopic features of the appendix that allow differentiation benign from malignant lesions, right hemicolectomy should be performed for tumors involving the periappendicular area or those larger than 2 cm in size [9] , [10] ; as was done in this case. However, there are cases in which making this decision intraoperatively is complex.…”

Mucinous carcinoma of the appendix is a rare malignant tumor of the appendix. Incidence ranges about 0.01-0.2% in cases of malignancy in the gastrointestinal tract. Clinically, the symptoms appear to resemble acute appendicitis. The diagnosis was established at intraoperative time. Studies on this case are still few. A 69-year-old man complained of lower right abdominal pain since 6 days before going to Sanjiwani hospital. The patient also complained of fever, nausea, decreased appetite and constipation. Examination results temperature 37.6 0C, McBurney sign (+), rebound tenderness (+), localized defense on lower right abdomen. Ultrasound examination of the abdomen with an impression of the end tubular structure, a peristaltic diameter of 0.87 cm accompanied by a fluid collection, suspicious of appendicitis with perforation. Inflamed appendix and localized mucin were found at ileocaecal junction intraoperatively. The patient underwent a right hemicolectomy. Histopathological examination revealed a morphological picture suitable for mucinous carcinoma of the appendix. Mucinous carcinoma of the appendix is a rare malignant tumor of appendix. Patients can have the same symptoms as appendicitis. Ultrasound investigations can find a picture like appendicitis. Mucinous carcinoma of the appendix is more frequently found intraoperatively. Histopathological examination is necessary to determine a definitive diagnosis of mucinous carcinoma of the appendix. In high grade appendiceal mucinous neoplasm (HAMN) a right hemicolectomy can be performed and continued with adjuvant chemotherapy.

Introduction: Appendiceal mucinous neoplasms (AMNs) are rare and account for 1% of gastrointestinal neoplasms and the diagnosis is mostly incidental. In spite of advances in the understanding of AMNs and their association with peritoneal disease, AMNs are still confusing entities in respect to their diagnosis and treatment alike. Case Report: We report a case of a 51year old female who presented with abdominal pain and vomiting and was diagnosed as ileo-colic intussusception on ultrasonography and CECT abdomen. Histopathological examination of right hemicolectomy specimen revealed a high grade appendicular mucinous neoplasm with low grade areas. The peri-appendiceal mucin deposition forming a mass in the cecum at the base of appendix was the lead point for intussusception in this case. No features of pseudomyxoma peritonei was seen in this case. This patient is well after 18 months of follow up period. Conclusion: Appendiceal mucinous neoplasms are rare and diagnosis is often difficult as presentation is mostly non-specific. Hence, awareness and further classification of these tumours is essential for diagnosis, determining the risk of recurrence and malignancy and also prognostication.
