Mucinous cystadenoma of the appendix with raised serum carcinoembryonic antigen concentration: clinical and pathological features.

A case of mucinous cystadenoma mimicking ovarian cancer is reported. Serum carcinoembryonic antigen (CEA) concentration was raised, and computed tomography of the abdomen and pelvis demonstrated a long oval shaped cystic mass measuring 9 cm in length on the right anterior side of the uterus. Because of possible right ovarian cancer, laparotomy was performed and the mass was found to be a mucinous cystadenoma of the appendix. This case indicates that mucinous cystadenoma of the appendix may show an unusual presentation including its location as well as the high serum CEA, mimicking ovarian cancer. Therefore, gynaecologists as well as gastroenterologists should consider its possibility as a differential diagnosis of the right adnexal mass in a patient without previous appendectomy.

Incidental mucinous cystadenocarcinoma of the appendix.

The incidental finding of a rare appendiceal tumour in a previously healthy male patient is described. He presented as an emergency with a self-inflicted abdominal stab injury. At laparotomy, there was no visceral damage but the appendix was hugely distended and appendectomy was performed. Subsequent histological examination of the appendix revealed a low-grade mucinous cystadenocarcinoma. A right hemicolectomy was performed two months later which demonstrated no residual tumour.

The appendix of the ventricle of the larynx.

A review of 100 consecutive laryngograms showed visualization of the appendix of the laryngeal ventricle in 40% of cases. This high incidence of visulization is related to thorough anesthesia, repeated performance of phonation and the reverse "E" maneuver as well as awareness of the anatomical structure. The appendix of the laryngeal ventricle courses superiorly between the laryngeal vestibule and the thyroid cartilage which differentiates this normal structure from ulcerations and fistulous tracts of laryngeal tumors.

Appendix epididymidis and aberrant ductules of the bull: light-microscopic and ultrastructural study.

The appendix epididymidis and aberrant ductules possessed similar morphological characteristics. The epithelium was 31 +/- 3 microns in height and consisted primarily of ciliated and nonciliated cells, although a few lymphocytes were also present. The ultrastructure of major cell types showed most cell organelles in their cytoplasm. However, these organelles were poorly developed, suggesting that neither cell type performed either a secretory or an absorptive function. Although the vestigial organs and ductuli efferentes were similar in epithelial height and epithelial cell types, there were important morphological differences that were reliably used to differentiate between the two. First, the luminal diameter was significantly smaller in the vestigial organs (60 +/- 12 vs. 146 +/- 44 microns in the ductuli efferentes). Second, the nonciliated cells of the vestigial organs, unlike those of the ductuli efferentes, lacked both dense granules and vacuoles in the cytoplasm. Finally, the tubular cross-sections of the vestigial organs were closely packed and were located at the tip of the caput epididymidis in the case of the appendix epididymidis, and between the lobules of the ductuli efferentes in the case of the aberrant ductules.

Primary mucinous cystadenocarcinoma of the appendix: CT findings.

OBJECTIVE: The preoperative diagnosis of a primary appendiceal tumor can be difficult because of its rarity and the paucity of material in the radiology literature. The purpose of this study was to describe CT findings in six patients with primary mucinous cystadenocarcinoma of the appendix. CONCLUSION: When CT reveals a cystic mass with enhancing wall nodularity in the expected area of the appendix, especially in older patients, the possibility of primary mucinous cystadenocarcinoma should be considered.

Perforated appendix in an inguinal hernial sac: Amyand's hernia.

A patient with a perforated appendix in a right inguinal hernial sac is reported. Some of the history of this condition is reviewed and a case is made that an appendix appearing in an inguinal hernial sac should carry the eponymous term "Amyand's hernia".

[An experience with a continent appendix stoma].

The submucosally embedded in situ appendix guarantees an ideal continence mechanism in patients with ileocecal urinary reservoirs. To date this modification of the Mainz pouch technique was performed successfully in 10 patients between September 1990 and October 1992. Pouch capacity ranged from 350 ml to 900 ml (mean: 565 ml), frequency of intermittent self-catheterization ranged from 3 to 7 times per day (mean: 4.4-5.4 times) and complete urinary continence without difficulty of self-catheterization was obtained in eight patients. Two patients with stomal stenosis needed to indwell a catheter. The follow up periods ranged from 3 to 24 months (mean: 14.7 months). The main advantages of appendix stoma technique are shorter operation time, a short ileal segment, no risk of nipple gliding or prolapse, no need for staples, thereby decreasing significantly the risk of stone formation, and facilitating easy catheterization. This method seemed to be valuable for continent urinary reservoir assuring patients of high quality of life.

Gastro-intestinal Kaposi's sarcoma, with special reference to the appendix.

Kaposi's sarcoma (KS) of the gastro-intestinal tract is a common disease in the AIDS setting, although it is often asymptomatic. In this paper we wish to highlight the occurrence of gastro-intestinal KS with appendiceal involvement. Two of the patients presented with features of acute appendicitis, and KS of the appendix was not suspected at the time of surgery. In the remaining patient KS of the appendix was part of generalised gastro-intestinal involvement. It is important to remember that KS can cause appendicitis by producing a submucosal nodule that abuts into the lumen and thereby causes obstruction. KS of the gastro-intestinal tract may therefore masquerade as 'simple' appendicitis, or indeed remain asymptomatic.

Is perforation of the appendix a risk factor for tubal infertility and ectopic pregnancy? An appraisal of the evidence.

OBJECTIVE: To critically assess the evidence that appendiceal perforation is a risk factor for subsequent tubal infertility or ectopic pregnancy. DATA SOURCES: Epidemiologic studies investigating the relationship between appendectomy and infertility or ectopic pregnancy were identified by searching the MEDLINE database from 1966 to 1997. Appropriate citations were also extracted from a manual search of the bibliographies of selected papers. STUDY SELECTION: Twenty-three articles were retrieved. Only 4 presented original data including comparisons to a nonexposed control group and they form the basis for this study. DATA EXTRACTION: Because the raw data or specific techniques of data analysis were not always explicitly described, indices of risk for exposure were extracted from the data as presented and were analysed without attempting to convert them to a common measure. DATA SYNTHESIS: Articles were assessed according to the criteria of the Evidence-Based Medicine Working Group for evaluating articles on harm. Review of the literature yielded estimates of the risk of adverse fertility outcomes ranging from 1.6 (95% confidence interval [CI] 1.1 to 2.5) for ectopic pregnancy after an appendectomy to 4.8 (95% CI 1.5 to 14.9) for tubal infertility from perforation of the appendix. Recall bias, and poor adjustment for confounding variables in some reports, weakened the validity of the studies. CONCLUSIONS: The methodologic weaknesses of the studies do not permit acceptance of increased risk of tubal pregnancy or infertility as a consequence of perforation of the appendix, so a causal relationship cannot be supported by the data currently available. Only a well-designed case-control study with unbiased ascertainment of exposure and adjustment for confounding variables will provide a definitive answer.

[Carcinoid of the appendix in incarcerated femoral hernia].

Carcinoid tumor can be found in the appendix in approximately 20% cases of all carcinoids located in gastrointestinal tract, which represents the main site involved by 75% of all carcinoids. Primary carcinoid of appendix has been found in 0.5% of all appendectomies. Femoral hernia is also rather rare pathology occurring among all hernias in less than five percent cases. We describe clinical observation of an exceptional combination of these two pathological entities presented as unexpected appendiceal carcinoid found within the incarcerated femoral hernia.

A new technique for resecting the non-inflamed not-adhesive appendix through a mini-laparotomy with the aid of the laparoscope.

A new technique for appendicectomy is described. Following detailed laparoscopic inspection of the abdomen, the appendix is pulled out with a laparoscopic forceps through a small incision in the right lower abdomen; it is then skeletized. Following ligation with catgut and nylon, the appendix is severed using the thermocautery. The stump is subjected to careful after-coagulation or treated with iodine, and repositioned. Only the skin is sutured.

Distant metastasis from a carcinoid tumor of the appendix less than one centimeter in size.

The presentation and management of a patient with liver metastasis from a 0.6 cm carcinoid tumor of the appendix is presented. This is the first documented case of distant metastasis from a carcinoid of the appendix less than 1 cm in size. Histopathologic, immunohistochemical, and electron microscopic studies support the appendiceal carcinoid as being the primary neoplasm. Invasion of the mesoappendix was the only finding to suggest potentially aggressive behavior. We reviewed the literature and found 414 previously reported cases that provided complete information regarding tumor size, mesoappendiceal invasion, and presence of metastasis. For the entire group the frequency of metastasis was related to tumor size greater than 2 cm (p less than 0.0001) and invasion of the mesoappendix (p less than 0.0001). After dividing the group based on size, mesoappendiceal invasion was related to metastasis in those tumors less than 2 cm in size (p less than 0.0001) but not in tumors larger than 2 cm (p = 0.1538).

[Primary adenocarcinoma of the appendix].

The authors published experience with the treatment of four patients with primary adenocarcinoma of the appendix and an analysis of 20 patients with primary adenocarcinoma of the appendix treated in the North Moravia region during a ten-year period (1980-1989). The incidence of the disease is rare. Usually it is manifested by symptoms imitating acute appendicitis. In exceptional instances there are other symptoms such as melaena, invagination, infiltration of neighbouring organs etc. Only rarely the disease is diagnosed during appendectomy. Most frequently an adenocarcinoma of the colonic type is involved with a tendency of rapid local spread. In that case right-sided hemicolectomy is the method of choice. In exceptional instances simple appendectomy is sufficient (mucinous type of adenocarcinoma, Dukes A). In advanced stages of the disease a palliative surgical operation may frequently suffice. Radiotherapy and chemotherapy should be always considered with regard to the stage of the disease and the general state of the patient. The prognosis is similar as in adenocarcinoma of the colon.

[Mucus-secreting tumors of the appendix: a preoperative diagnosis is possible. Apropos of 2 cases].

The authors present two cases of pseudo tumoral type Mucus Secreting Tumours (MST) of the appendix. In this type (32% of the cases), the clinical presentation, barium enema, ultrasonography and most importantly CT scan generally confirm the preoperative diagnosis. We found three advantages this preoperative diagnosis. 1) Primarily it allow selection of a large surgical approach that permits full exploration of the abdominal cavity especially the ovaries (2-18% associated lesions); 2) also it allows a histopathological examination (frozen section) of the appendix to be performed during the operation; 3) and finally the surgical treatment will depend on the operative findings and the result of the histopathological examination: in the benign forms simple appendicectomy will be sufficient but the malignant forms (12% of the cases) should be treated by right hemicolectomy.

[Benign mucus-secreting tumors of the appendix. Six cases].

The authors report six cases of mucus-secreting tumor of the vermicular appendix, in four women and two men (mean age 59 years). All were benign. Pain in the right lower quadrant was the initial sign in 4 cases, while the mucus-secreting tumor was an incidental finding in the other two cases. A mass was palpated in the right lower quadrant in one case. A barium enema was performed in four cases and showed an extrinsic compression of the caecal base in one case, and of the right colon in another case. Four appendectomies, one associated with removal of the adjacent caecal tissues and two right colectomies were performed. Analysis of these six cases and a review of the literature allow us to recall the histologic classification of these tumors, which determines the prognosis and to emphasize the sonographic and CT scan findings which might lead to earlier preoperative diagnosis in the future. Management depends upon the circumstances under which the tumor is discovered, the local anatomy, and the type of tumor. Appendectomy is the treatment most often performed. Faced with a tumor of the appendix, without histologic proof or when the local anatomic conditions increase the risk of opening an abscess, right colectomy is recommended.
