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.

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.

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.

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.

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.

Actinomycosis is a chronic infection, which mainly affects of the cervicofacial area, thorax or abdomen, and is caused by anaerobic Actinomyces. The predilection site of abdominal involvement is the appendix and cecum. Although perianal actinomycosis as a secondary site of abdominal actinomycotic disease is a well known presentation, primary perianal actinomycosis without involvement of the internal organs is rare. We report a case of primary perianal actinomycosis. A 65-year-old male presented with a recurrent perianal abscess. Histopathologic findings showed acute and chronic inflammation with characteristic sulfur granules, composed of many basophilic, rod-like, Gram-positive bacilli, indicative of actinomycosis.

Appendiceal intussusception is a rare disease entity and appendiceal mucocele is one of the causes of this disease. Although computed tomography, ultrasonography, barium enema and colonoscopy can be performed to make a preoperative diagnosis, only a few cases of appendiceal mucocele-induced intussusception have been precisely diagnosed by these diaggnostic tools. Most of all, few such cases have been confirmed by colonoscopic examination. Colonoscopic examination has a supplementary role for the differential diagnosis of acute or chronic appendicitis, tumor or abscess in the ascending colon and cecum that is caused by appendiceal intussusception. We report here on a case of intussusception that was caused by an appendiceal mucocele, and this showed a target appearing structure in the hepatic flexure and a cystic mass inside the intussusceptive lumen on abdominal CT, and a huge mass was discovered on the colonoscopic examination.

Myxoglobulosis is a rare morphologic variant of appendiceal mucocele. We reported herein a case of myxoglobulosis in a 50-year-old man who presented with an appendiceal mass following a several months symptomatic course. Double contrast barium study showed filling defect in cecum. Computed tomograph showed well defined tubular, cystic lesion with slight wall enhancement at the appendiceal area. Laparotomy disclosed a distended appendix, measuring 12.0 4.0 cm, without perforation containing white to pale yellowish globules, reminiscent of parasitic eggs. Microscopically globules are composed of centers of inflamed granulation tissue and amorphous granular necrotic debris, surrounded by rings of inspissated mucous shells. The wall shows devoid of a lining epithelium. We performed ileocecectomy.
