Clinicopathologic correlation and survival were evaluated in 11 patients with adenocarcinomas of the appendix. This extremely rare tumor was seen most often in patients in the fifth decade of life. Acute appendicitis was the most common mode of presentation (8/11). A few patients (3/11) showed signs of distant metastases from an occult primary tumor in the appendix.

A case of carcinoma of the caecum is reported, which presented as acute appendicitis, although the carcinoma did not obstruct either the lumen of the appendix or the colon. The prognosis for caecal or proximal colonic neoplasm presenting as appendicitis is poor. This is in part due to the association being missed at the initial laparotomy. It is suggested that a more aggessive attitude should be taken in the pre- and post-operative management of any patient over 50 years of age who presents with appendicitis. The difficulties of identifying a small tumour at laparotomy even if the mucosa can be palpated are emphasized.

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.

Thermography appears to be a useful supporting aid to classical methods of examination in the clarification of the problems of acute abdominal disease. In a study of 100 patients thermography was in support of the true diagnosis in acute appendicitis in 63 per cent, in acute biliary tract disease in 59 per cent, and, in an attempt to differentiate between tumor and periappendicular abscess, assistance was rendered by thermography in 53 per cent of patients. However, some uncertainty exists because carcinoma often produces in its environment an inflammatory reaction, which causes an increase of temperature visible in the thermogram. In the present series thermography produced a finding supporting the correct diagnosis in 59 per cent. Errors occurred most often in obese patients, who have thick abdominal covers. Thermography also has an obvious application in the localizing of postoperative suppurative foci.

Apendicular Carcinoid tumors are very infrequent, being lower than 0.1% of the appendicectomies carried out. We report on the case of a 13 year-old girl, with Acute Appendicitis picture. The appendix was removed and the histological study revealed the presence of the carcinoid tumor with a diameter of a 6 mm. Where non-invasive treatment was decided on, and at present, after two years follow-up, there has been no recurrence.

Over a 3-year period nine patients (mean age of 43 years) with acute abdominal pain and unsuspected abdominal neoplasms were referred for graded compression sonography to rule out appendicitis. Six of the nine patients had right lower quadrant neoplasms involving the cecum, terminal ileum, iliacus muscle, or iliac lymph nodes. However, in three patients neoplasm was noted outside the right iliac fossa involving the liver, right kidney, and upper abdominal mesentery. This study underscores the fact that in patients without sonographic evidence of acute appendicitis, a survey of the upper abdomen and right flank should routinely be performed in addition to scanning the right iliac fossa and pelvis. In patients more than 50 years of age neoplasm must also be kept in mind in the differential diagnosis of appendicitis.

An 8-year-old girl presented with the clinical features of acute appendicitis. The removed appendix was normal but the abdominal pain persisted. There were no urinary symptoms and bacteriological examination of the urine was negative. An ultrasound scan showed an intravesical tumor that was subsequently excised. Histology showed a grade 1 transitional cell papillary bladder carcinoma of low grade malignancy. All previously reported cases have presented with urinary tract symptoms, usually hematuria.

A case of cystic mesothelioma of the peritoneum, presenting as acute appendicitis is reported. The authors stress the difficulty of a correct preoperative diagnosis of this rare tumor, which however, may be considered benign, with a good long-term prognosis.

The authors studied the data concerning 101 patients who had undergone erroneous laparotomy for suspected acute surgical disease; these accounted for 0.4% of all the patients who were operated on for emergency indications in the same period. Eleven patients died. The operation was undertaken for an erroneous diagnosis of acute appendicitis (32 patients), acute cholecystitis (18), perforating gastric ulcer (15), peritonitis of unknown etiology (14), acute intestinal obstruction (5), strangulated hernia (3), destructive pancreatitis (3), tumor of the large intestine complicated by obstruction (3), abdominal abscess (2), thrombosis of the mesenteric vessels (1), ovarian apoplexy (1), closed abdominal trauma with injury to the viscera (4 patients). Diseases simulating the clinical picture of "acute abdomen" but not requiring an emergency operation were as follows: female reproductive (20 patients), pancreatic (11), renal diseases (11), hepatitis, cirrhosis of the liver (10), cardiovascular (9), pulmonary diseases (5), mesoadenitis (5), Crohn's disease (3), chronic colitis (3), carcinomatosis of the peritoneum (3), herpes zoster (3), and other diseases and injuries (20 patients). The main causes of the diagnostic and tactical errors were objective difficulties in the differential diagnosis due to similar symptomatology, as well as errors in the examination of the patient and haste in making a decision to make an operation.

The present article is based on a review of 187 patients with an ovarian cancer who had a "second-look" or debulking operation performed. Seventy-nine patients underwent appendectomy prior to or in connection with the primary cytoreductive surgery and were observed for a average of 16.6 months before secondary oncologic surgery was performed. The remaining 108 patients had their appendix in situ during the same period and were observed for an average of 14.7 months and 1 patient developed acute appendicitis. A total of 125 appendectomies were performed in patients with cancer of the ovary and 14 (11%) showed metastatic growth. The two groups were similar as regards age, period of observation, tumor type and stage. The risk of developing acute appendicitis did not exceed the incidence in healthy women and no surgical problems were experienced in observing either of the two groups during the total period of 2,900 months. The need for surgical surveillance, however, was significantly greater for those who kept their appendix during the medical oncologic treatment. It is concluded that the cytoreductive effect of an appendectomy is limited, but that the appendix should be extirpated if possible as part of the primary staging effort. Leaving an appendix in situ at primary cytoreductive surgery does not expose the patient to any significantly increased risk, but an appendectomy prevents the patient from experiencing the additional burden of an acute appendicitis during medical oncologic treatment.
