Mucocele of the vermiform appendix was the term formerly used to describe all mucin-secreting lesions of the appendix. In actuality, there are three distinct clinicopathologic entities based on histologic differences. These are mucosal hyperplasia, cystadenoma, and mucinous cystadenocarcinoma of the appendix. Mucosal hyperplasia is usually an incidental finding during laparotomy for an unrelated condition. The case presented herein differed in that the patient had a three-month history of abdominal pain with nothing to suggest the presence of appendicitis, and a 3-cm opacification overlying the right iliac bone on x-ray.

Mucocele of the appendix was first described and named "Hydrops processus vermiformis" by Rokitansky in 1866. Intussusception of a appendiceal mucocele is very rare and we have been able to find only 14 previously reported cases. We present two cases with preoperative ultrasonography which is valuable for its diagnosis. Case 1: A 5-year-old male was admitted to Kahoku Hospital because of right lateral colic abdominal pain and tumor. Ba-enema examination revealed intussusception to the colon and ultrasonography showed the cystic mass of the appendix. Case 2: A 51-year-old female was admitted because of right lower abdominal pain. Ultrasonography was helpful showing the cystic tumor at the base of the appendix. Recent reports say that ultrasonography is valuable examination for its diagnosis. Also in our two cases preoperative ultrasonography was performed and gave us valid information for its qualitative diagnosis.

A 38-year-old female with systemic lupus erythematosus presented with abdominal pain, diarrhea and iron-deficient anemia. Computed tomogram showed a 2 x 4 cm inhomogeneous lesion of the right adnexa. An unusual mass was identified extending from the appendiceal orifice at colonoscopy, and an 8 cm tubular appendix, apparently prolapsed into the cecum, was identified at celiotomy. An appendectomy with cecectomy was performed. On cut section, mucin was extruded from the lumen of the appendix. A mucinous neoplasm of the appendix with mucinous dissection to the serosal surface was reported at the time of frozen section. No gross ovarian pathology or peritoneal implants were noted. Cystadenoma with associated mucocele formation was verified by permanent histology. Mucocele of the vermiform appendix is a rare condition associated with neoplastic transformation in approximately 75% of all cases. Benign mucinous cystadenoma of the appendix should be differentiated from cystadenocarcinoma by frozen section at the time of celiotomy to ensure appropriate treatment. While systemic lupus erythematosus can lead to cutaneous mucinosis, an association with mucinous cystadenoma of the appendix has not been previously reported. Surveillance for metachronous colonic neoplasms is warranted in patients diagnosed with a mucinous neoplasm of the appendix.

Mucocele of the appendix is a nonspecific term that is used to describe an appendix abnormally distended with mucus. This may be the result of either neoplastic or non-neopleastic causes and may present like most appendiceal pathology with either mild abdominal pain or life-threatening peritonitis. Urologic manifestations of mucocele of the appendix have rarely been reported. Laparoscopy can be used as a diagnostic tool in equivocal cases. Conversion to laparotomy may be indicated if there is a special concern for the ability to remove the appendix intact or if more extensive resection is warranted, as in malignancy. We here report our experience with a woman presenting with hematuria whose ultimate diagnosis was mucocele of the appendix, and we review the appropriate literature. This case highlights the mucocele as a consideration in the differential diagnosis of appendiceal pathology and serves to remind the surgeon of the importance for careful intact removal of the diseased appendix.

Mucocele of the appendix is an uncommon disorder, characterized by a cystic dilatation of the lumen. It is often diagnosed clinically from signs and symptoms of acute appendicitis or, if it is asymptomatic, as an incidental finding during ultrasonography, computed tomography, and radiographic examinations of the gastrointestinal tract, or laparotomy. The incidence of mucocele ranges from 0.2% to 0.3% of all appendectomy specimens. We report five cases of appendiceal mucocele (all women, aged 19-90 years), who were admitted from January 1993 to January 2003 to our hospital. These cases represent 0.29% of the 1720 appendectomies performed during this period. Three of the patients were symptomatic and had appendectomies. The final diagnosis for mucocele was given at laparotomy. No colon neoplasms were identified during surgery, and subsequent colonoscopic examinations were also negative. The other two patients were asymptomatic of appendiceal tumor. Colonoscopy revealed two colonic malignant tumors in one patient and an adenocarcinoma of the sigmoid colon in the other. Mucocele of the appendix was diagnosed pre-operatively by ultrasound and computed tomography. One of the two patients underwent a right hemicolectomy and sigmoidectomy; the other one underwent an appendectomy, cecostomy and sigmoidectomy. Four of the patients recovered and are doing well today; one patient died on the twenty-fifth postoperative day. The most common symptom of mucocele is abdominal pain, although many patients may be asymptomatic. Mucocele is often associated with concomitant colon cancer, thus patients with this tumor should be systematically checked for other colonic lesions.

Mucocele of the appendix is a thin-walled dilated appendix filled with mucus. It occurs secondary to chronic obstruction of the appendiceal lumen because of a range of pathologies. Cystadenomas in children are exceedingly rare and most frequently of ovarian origin. A mucous cystadenoma of the appendix in a 10-year-old boy with chronic abdominal pain is presented.

Mucocele of the appendix is a rare entity, characterized by distension of the lumen caused by an accumulation of mucoid substance. We report herein the case of a 73-year-old man with a 3-week history of abdominal pain caused by a large mucinous cystadenoma. The lesion was removed intact, which is the optimal treatment.

Mucocele is a mucin-filled cavity, which can be multi-loculated as well. Mucocele is relatively rarely found in the appendix. The disease does not cause any symptoms in most cases, and it is usually an accidental finding. A thorough investigation should be carried out to exclude malignancy. Depending on the operative findings and the full histological report, the spectrum of surgery extends from appendectomy to right hemicolectomy. In this paper, we discuss the presentation, diagnostical options, and the possible surgical treatment--based on our experience with five cases. In three cases a non-tender mass was palpable in the right lower quadrant of the abdomen, while another patient presented with right lower quadrant abdominal pain and one with abdominal pain and diarrhoea. Abdominal and pelvic ultrasound and CT scans raised the possibility of mucocele, however colonoscopy was negative. After laparoscopic exploration, laparoscopy assisted partial caecum resection was carried out in two cases, in further two cases laparoscopic appendectomy, and in one case laparoscopic partial caecum resection was done. The hystological examinations showed appendiceal mucocele with no malignancy demonstrated. All patients recovered without complications, they were discharged from hospital on postoperative day five. The patients have been disease free after a 6-30 month follow-up period. We concluded that laparoscopy is a recommended method for the surgery of appendiceal mucocele.

Mucocele of the appendix due to mucinous cystadenoma is a rare clinical finding. Approximately half of the patients are asymptomatic. It's defined as the dilatation of the appendiceal lumen due to abnormal accumulation of mucus in to it. The pseudomyxoma peritonei, as a result of rupture of the appendix, is the most dangerous complication. We present two case reports of patients that were presented in our Department with different clinical findings. The first patient was presented with symptoms of acute appendicitis, while the second patient showed with atypical symptoms such as abdominal pain, a palpable mass in the right iliac fossa and a diagnosed mucocele of the appendix with the use of computerized tomography. In both patients was performed an appendicectomy and the final histopathology diagnosis confirmed the presence of the mucinous cystadenoma of the appendix which caused the creation of the mucocele. In conclusion mucocele is a rare tumor which must be considered in the differential diagnosis of a mass in the right lower quadrant of the abdomen.

Mucocele of the appendix due to endometriosis is extremely rare, and there are only 10 previously reported cases in the English literature. We report a case of mucocele of the appendix due to endometriosis and provide the first review of the literature. A 43-year-old woman was admitted to the hospital because of recurrent right lower abdominal pain during her menstrual periods. Colonoscopy revealed submucosal tumor-like elevations of the appendiceal orifice. Computed tomography and magnetic resonance imaging of the abdomen suggested cystic lesions near the appendix. Consequently, mucocele of the appendix was suspected preoperatively. An open ileocecal resection was performed. Multiple cystic lesions were observed around the appendix. The cystic lesions contained mucus. Histopathological examination was consistent with a mucocele of the appendix due to endometriosis. The postoperative course was uneventful. We present the first review of the literature to clarify the clinical features.
