A 51-year-old gravida 5 para 5 (5005) presented with an increasing abdominal girth and a palpable abdominal mass. She was initially diagnosed with ovarian new growth and underwent exploratory laparotomy. Intraoperatively, the uterus, Fallopian tubes, and ovaries were grossly normal and a large mass was seen attached to the cecum where the appendix should be referral to surgery service was done. Right hemicolectomy and ileostomy were performed. The histopathology report was “suggestive of a Müllerian adenosarcoma (MAS) involving the appendix and cecum.” Microscopic examination showed evidence of endometriosis with no evidence of sarcomatous overgrowth, features that are favorable prognostic factors associated with higher disease-free survival. Postoperatively, the plan of management was hormonal therapy. Extragenital MAS is rare. This case is the fourth case to be reported in the literature to arise from the colon. Although there is still no standard of treatment, accurate diagnosis is imperative for appropriate management.

Appendiceal mucoceles are rare lesions. There has been only one report of a mucocele of the remnant appendix not communicating with the cecum. We report a remnant appendiceal mucocele following an incomplete incidental appendectomy, which presented as a lobulated cystic mass on ultrasonography and a cystic mass with an irregular wall on computed tomography. A borderline malignant mucinous tumor of the appendix was diagnosed.

PURPOSE: To evaluate the usefulness of CT features of appendiceal mucocele in the diagnosis and evaluation of complications. MATERIALS AND METHODS: We retrospectively reviewed CT findings and compared with operative findings in 7 cases of pathologically proven appendiceal mucocele. CT findings such as location and extent of the lesion, Issue density, thickness or calcification of the wall, presence of adjacent inflammatory infiltration, and visualization of normal vermiform appendix were analyzed. RESULTS: Appendiceal mucocele was found as homogeneous low density cystic mass adjacent to the cecum, which has no surrounding inflammatory infiltration except in one case of perforation and one case of intussusception. Mean CT number measured in 4 cases was 21 Hounsfield unit. Thin curvilinear calcifications were noted along the cystic wall in 2 cases. Normal vermiform appendix couldn't be demonstrated in all cases. CONCLUSION: Appendiceal mucocele is characterized by homogeneously low density and thin walled cystic tumor adjacent to cecum without surrounding inflammatory infiltration, and absence of normal vermiform appendix on CT. Therefore, CT is valuable in preventing operative complications of appendiceal mucocele.

Once ingested foreign bodies pass through the stomach, 80 to 90 percent of them will exit via the gastrointestinal tract and they are excreted naturally in 7-10 days; surgical treatment is not required in most case. But once foreign bodies permeate the appendix, it is difficult for them to be excreted again to the cecum; therefore, this can possibly cause appendicitis or perforation. Especially in case of long, pointed, thin, stiff, sharp and/or metalic objects, the risk of perforation will increase. We attempted to remove an endodontic file in the appendix by colonoscopy. This was done in a patient who came to hospital because he swallowed an endodontic file during endodontic therapy. But we failed to retrieve it, and so we got rid of the foreign body by performing elective surgery before the occurrence of complications. We report here on surgical removal of an apppendiceal foreign body along with a review of the literature.

The appendiceal mucocele is a rare disorder, usually found incidentally during ultrasonography or radiologic studies. Mucoceles of the appendix include benign or malignant disease. Both of benign cystadenoma and malignant cystadenocarcinoma are characterized by an obstructed, mucin-filled appendix displacing the cecum. We experienced a case of partial obstruction of large bowel who had a cystadenoma at appendix and a colon cancer at other site on operation field. Here in, we report a case of appendiceal mucocele and concominant colon cancer with the review of literatures.

We report a case of intussusception of the cecum and appendix arising in pericecal endometriosis that are mistaken as a cecal tumor preoperatively. At the other OBGY clinic, the 1st lapalotomy was performed for management of leiomyoma but pelvic organs were adhesion severely and palpation mass in the cecum and appendix. The patient was transfer to our hospital for evaluation and treatment of mass. We investigated to intestine closely and diagnosis was cecal tumor colonoscopically. Total hystrectomy and iliocecectomy was performed successfully and discovered intussusception of the cecum and appendix due to endometriosis mistaken as a cecal tumor in operative field. Postoperatively, this case was diagnosed in pericecal endometriosis histologically.

The appendix has been reported to be a very rare leading point in intussusception. Therefore, preoperative diagnosis can rarely be made. We experienced one case of appendicocecal intussusception in a 2-year-old girl. An air contrast study done during air reduction suggested a cecal mass, and a saline filled sonogram showed a polypoid lesion in the cecum. The lesion turned out to be an intussuscepted appendix in appendicocecal intussusception.

Stump appendicitis is an acute inflammation of the residual appendix and is a rare complication after appendectomy. The physician should be aware of the possibility of stump appendicitis in patients with right lower abdominal pain after appendectomy so that delayed diagnosis and treatment can be prevented. Stump appendicitis is usually treated by surgical resection, and endoscopic treatment has not been reported previously. A 48-year-old man who had undergone appendectomy 35 years earlier presented to the hospital because of right lower quadrant discomfort. A computed tomography scan showed a large stone in the residual appendix. Colonoscopic findings revealed a large, smooth, protruding lesion at the cecum with a stone inside the appendiceal orifice. Endoscopic removal after incision of the appendiceal orifice was performed successfully.

Appendiceal intussusception is a very rare pathological condition, an incidence, as revealed by appendectomy specimens, of only 0.01 percent. There are various types among which complete invagination of the appendix is very rare. We encountered a case of intussusception of the appendix with complete invagination induced by appendiceal adenocarcinoma. A preoperative diagnosis of appendiceal adenocarcinoma and intussusception was not possible, but a final pathological report confirmed these conditions and retrospective analysis of a barium enema showed a finger-like filling defect of the cecum, a relatively specific finding in such cases. We describe a case involving a 39-year old man who one month earlier had noted the onset of pain in the right lower abdomen.

Carcinoid is a tumor that primarily affects the intestinal tract, which arises from entero-chromaffin cells. Rectal carcinoid tumor is a relatively rare neoplasm originated in Kul-chitszky cell and clinicians have the difficulties in predicting their malignant potential and in proper treatment. These cells are found to increase in the distal small intestine, are common in the appendix, and then decrease within the mucosa of the colon from cecum to rectum. In the cumulative world literature, the incidence of carcinoids of rectum is slightly higher than 10 percent. All of these tumors are within reach of the rigid procto-sigmoidoscope, most being located between 4 and 13 cm from the anal verge. Eighty five percent are found on the anterior and lateral walls. The tumors are usually submucosal and light yellowish or reddish color. The vast majority of rectal carcinoid tumors are be-nign, which can be treated by local excision safely. Lesions larger than 2 cm and invading the muscular wall of the rectum should be considered malignant, which are treated by more radical surgery such as abdominoperitoneal resection. We experienced a case of rectal carcinoid tumor, which was excised by endoscopic polypectomy, so we present this case with a review of relevant literatures.
