This report is a retrospective evaluation of 12 case histories. All patients had been subjected to laparotomy on suspicion of acute appendicitis. The operative situations seemed to corroborate clinical expectations: an inflamed ileocecal process was assumed to be a result of performation of a gangrenous appendicitis. In three patients a primary adenocarcinoma arising from the appendiceal base was the incidental histologic finding postoperatively. In three other patients this inflammatory-looking process was related to a cecal carcinoma. In six patients a carcinoma existed unrecognized as the basic disease, these patients being subjected to intra-abdominal drainage only or in connection with appendectomy. In five instances a fecal fistula was the main persisting symptom of postoperative morbidity, in one patient even as long as two years after laparotomy. The problem in diagnostic verification of the initially unidentified carcinoma is illustrated. Attention is directed towards avoiding a false feeling of security in the presence of inflammatory manifestations in the right lower abdominal quadrant, which may misleadingly suggest a ruptured appendix.

The pathological changes occurring in a series of 1000 consecutive appendicectomies are reviewed. Normal appendix was diagnosed in 14% of cases, while 561 (56%) exhibited acute appendicitis; 53 (5%) had chronic inflammatory infiltrate associated with obliteration of the lumen of the tip of the appendix. Epithelial abnormalities included carcinoid tumours (1.4%), and primary appendiceal adenocarcinoma (1 case). There were a large variety of other abnormalities found and each one is briefly described.

An analysis of 101 tumors of the appendix is presented. During the period under study (from 1949 to 1972), 8,699 appendectomies had been performed. Only 17 of the 101 tumors were malignant. In this group, there were two primary carcinomas, 12 metastatic carcinomas, and three lymphomas. Most of the tumors (84) were benign, including 43 carcinoids, 32 mucoceles, five neuromas, two leiomyomas, and two villous adenomas, Some of the clinical and pathologic features of carcinoids, adenocarcinoma, and mucoceles are discussed. The most significant observation in this study is the statistically significant evidence that, even without associated acute appendicitis, mucoceles 2 cm or more in diameter probably do cause clinical symptoms, which may be alleivated by appendectomy.

A case of primary adenocarcinoma of the appendix in which the patient had the usual symptoms of acute appendicitis is presented. A review of the literature showed the potential for early extension and nodal metastasis in this lesion and led to the recommendation of right hemicolectomy as the treatment of choice. The operation should be done either primarily or secondarily after an appendectomy and should lead to a five-year survival of approximately 45%. Every effort should be made to make the diagnosis and provide definitive treatment at the primary operation by examining the appendix grossly and obtaining frozen section microscopic study of any suspicious tumor or ulceration.

Adenocarcinoma of the vermiform appendix is rare. It usually produces signs of acute appendicitis and is discovered only on pathological examination. The treatment of choice is right hemicolectomy, usually performed as a secondary operation. 2 cases of appendiceal carcinoma, in a 59-year-old man and in a 70-year-old woman, are described.

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.

We report seven cases of adenocarcinoma of the vermiform appendix occurring in Iceland during 1974-1989. The patients ranged in age from 25-83 years, mean age 55.1 years. There were five males and two females. Five had mucinous adenocarcinoma, two had adenocarcinoma. Four patients presented with symptoms and signs of acute appendicitis and all had surgically resectable disease. Three of these patients were alive with no evidence of disease four months, two years and 15 years after presentation; one death of disease occurred seven years after ileocecal resection. In three cases, the clinical presentation was that of metastatic adenocarcinoma of unknown origin. Of these patients two were diagnosed at autopsy and one after appendectomy for perforated appendicitis. Survival in this group was six weeks, three months and twelve months, respectively. In none of our patients was the diagnosis made preoperatively and no tumors were found in appendices removed incidental to other intra-abdominal operations. The incidence of adenocarcinoma of the vermiform appendix in Iceland during 1974-1989 was approximately 0.2 cases/100.000/year.

The successful application of laparoscopic surgery to gallbladder disease and acute appendicitis has encouraged clinical investigators to develop this technology further in an attempt to manage other pathologic disorders of the gastrointestinal (GI) tract. After gaining experience with various laparoscopic skills while performing clinical biliary tract surgery, appendectomy and then in a controlled animal laboratory, a pilot program for laparoscopic colonic surgery was initiated. Twenty patients with ages ranging from 43 to 88 years (mean age of 57 years) underwent laparoscope-assisted colon resection. In nine patients, a right hemicolectomy was performed and a sigmoid colectomy in eight. A low anterior resection, Hartman's procedure, and abdominal perineal resection were each performed in one patient. Indications for surgery were large villous adenomas or adenocarcinoma in 12, diverticular disease in 5, sigmoid endometrioma in 1, cecal volvulus in 1, and inflammatory bowel disease in 1. Eighty percent of patients were able to tolerate a liquid diet on the first postoperative day and 70% were discharged within 96 h eating a regular diet and having normal bowel movements. There were three operative complications: a 3 unit postoperative bleed managed without surgery, one patient developed marked edema of the rectosigmoid anastomosis requiring decompression with a rectal tube, and one individual with metastatic colon cancer was operated on for a mechanical small bowel obstruction 7 days after the initial laparoscopic surgery. Although laparoscope-assisted colonic surgery may still be considered a procedure in evolution, we feel that in time it has the potential to be as popular as laparoscopic cholecystectomy.

A review of cases of primary adenocarcinoma of the appendix seen at the Hines VA Hospital (1950-1987) and Loyola University Medical Center (1977-1987) revealed a total of 14 cases. All patients presented with a clinical picture suggesting acute appendicitis or a right lower quadrant mass. Malignancy was not suspected in any of the patients prior to surgery. The age group ranged from 25 to 66 years (mean, 51.8 years) with 29% of the patients under 45 years old. The presence of carcinoma should be carefully looked for in middle-aged and elderly patients presenting with acute appendicitis.

Primary adenocarcinoma of the appendix is an uncommon disease frequently diagnosed surgery. It has an occurrence between 0.01 and 0.11% of all appendectomized patients, and it is more often found in patients older than fifty years. Symptoms are usually similar to those seen in acute appendicitis. Some authors consider the mucocele of the appendix a primary carcinoma as it is related with obstruction of the appendix lumen followed by a cystic dilatation with mucosal changes, mucus hypersecretion and extension outside of the appendix. We present one case with abdominal pain, constipation, weight loss of 26 kg, and a mass localized in the right lower quadrant. An exploratory surgery showed a partially retroperitoneal mass of 15 by 20 cm, irregular, cystic, with mucus content and the appendix included in it. The mass was removed and appendectomy was performed. Postoperatively the patient did well. The final pathologic report was a cystadenocarcinoma of the appendix.
