The association of appendicitis with schistosomiasis in the appendix is extremely rare in France. We report herein a new case in which the diagnosis was made, in the presence of pseudo-tumoral appendicitis, by frozen section biopsies. The patient presented with a typical acute appendicitis, without urinary symptoms, and with granulocytosis (14000 white cells/mm3, without eosinophilia). At laparotomy, the appendix was voluminous, with necrotic abscess, and lymph node masses were noted on the greater omentum. Frozen section biopsies of an omental tumor showed schistosoma eggs, without malignant cells. Appendicectomy and partial omentectomy were performed. Postoperative course was uneventful. Pathologic examination of the resected specimen showed schistosoma eggs in all layers of the appendix, and in the omentum. Final diagnosis was established by positive serology and by findings Schistosoma haematobium eggs in the urine. The patient was treated postoperatively by praziquantel. In conclusion, in case of acute appendicitis, with pseudotumorous appendix and lymph node masses, even with poor epidemiological findings on the clinical history, frozen section biopsies can sometimes establish the diagnosis of schistosomiasis with appendicitis, and avoid unjustified bowel resection.

During April to August 1992, laparoscopies were performed in this department in 35 of 100 cases of appendicitis. The average patient age was 29 years; 18 of the 35 (51%) were women; 3 patients were operated on electively, and the rest as emergencies. Appendectomy was performed in 33 (94%), but not in 2 women with sepsis due to tubo-ovarian abscess; In 1 of these 2 we had to convert to laparotomy. Acute appendicitis was found in 20 (57%). In 7 women (20%) gynecologic disease was diagnosed. In 1 case (3%) a carcinoid tumor of the tip of the appendix was found and in another primary peritonitis. In the remaining 6 (17%) no lesions were found. In 33 (94%) a regular diet was resumed 25 hours postoperatively and 25 (71%) were discharged the day after operation. The only complication was an abdominal wall hematoma in a single case, which resolved spontaneously. It is our impression that laparoscopy is a useful diagnostic tool in acute appendicitis, that it is a safe route for appendectomy, and that recovery is quick with minimal complications.

A retrospective review of 2,216 patients surgically treated for a clinical diagnosis of acute appendicitis was performed. In 80% of cases, histologic acute appendicitis was found; 57% of these patients were male. The rate of normal appendectomy was 16%, and females comprised 68% of that group. The remaining 102 cases (4%) were designated as the alternate diagnosis group. Apart from histologic diagnoses that could be considered variants of normal (57) or acute inflammation (20), the alternate diagnosis group included such entities as neoplasm, parasitic infection, mucocele, and diverticulitis.

The acute abdomen in childhood is in most cases caused by an acute appendicitis and rarely it is secondary to other diseases. It is for that reason, that we present two cases extremely rare of acute abdomen: the first one was an abdominal Actinomycosis secondary to acute appendicitis that looked like a tumor and the second that was an acute omentitis due to pinworms.

Diverticulum of the right colon is a rare disease which is often wrongly diagnosed and asymptomatic. It affects young individuals and is manifested by symptoms similar to appendicitis. The paper reports a case of a young man with an isolated perforated diverticulum of the right colon which was clinically manifested as acute appendicitis with peritoneal reaction. It is extremely difficult to make a preoperative diagnosis of cecal diverticulitis. Even the anatomosurgical appearance sometimes makes it difficult to distinguish from neoplasia. For this reason the most frequent operation is right hemicolectomy which is however well tolerated by young patients.

The authors describe a case of acute diverticulitis of the appendix presenting as an inflammatory mass in the right lower quadrant of the abdomen. The histologic and clinical findings are discussed. This uncommon condition may mimic acute appendicitis, but in most instances it departs from typical appendicitis for later age of appearance, more indolent clinical course and increased tendency to perforation. In these cases the disease may progress with subacute interstitial inflammation, with or without abscess formation, and present as a tumor-like mass of the cecum.

We report a case of salivary duct carcinoma in a 47-year-old woman. The patient presented with symptoms simulating acute appendicitis. Surgery revealed metastatic tumor in the wall of the small bowel. Two months later, a tumor of the right parotid gland was resected, and histologic analysis revealed a salivary duct carcinoma. To our knowledge, this is the first case of salivary duct carcinoma metastasizing to the small bowel with manifestations of metastatic disease as the prominent symptom.

We report a case of colonic type adenocarcinoma of the appendix with perforating peritonitis in a 92-year-old man. The preoperative diagnosis was localized peritonitis due to acute appendicitis and emergency laparotomy was performed. A gray, hard tumor was palpated at the base of the appendix. Appendiceal cancer was suspected, and right hemicolectomy was performed. The histopathological diagnosis was moderately differentiated adenocarcinoma of the appendix. The tumor obstructed the orifice of the appendix, and this may have caused the perforation of the appendix. The patient had an uneventful postoperative course and there have been no signs of recurrence in the 2 years since the operation.

Ultrasound is useful in the assessment of patients with possible appendicitis. A diagnosis of appendicitis can be made in patients with persistent right lower quadrant pain when a non-compressible appendix greater than 6 mm in diameter is shown. When a normal appendix is affected by an adjacent lesion, reactive inflammation can cause secondary enlargement of the appendix. This article reviews ultrasound findings in conditions which can clinically mimic acute appendicitis. Examples of Crohn's disease, tuboovarian abscess, typhilitis, sigmoid diverticulitis, perforated sigmoid neoplasm, perforated peptic ulcer, perforated acute cholecystitis, caecal carcinoma and appendiceal tumours are included.

Indications and contraindications to laparoscopic surgery continue to be refined. Laparoscopic appendectomy for acute appendicitis is frequently selected by patients and surgeons, and clinical studies show it to be a reasonable alternative. In this case study, laparoscopic surgery was used to resect an appendiceal mucocele caused by a nonperforated mucinous adenocarcinoma. Implants of mucinous tumor were found widely disseminated on peritoneal surfaces at laparotomy 9 months later. As a result of this case study, the authors suggest that when an appendiceal mucinous tumor is encountered at laparoscopy, a special situation requiring totally atraumatic appendectomy is indicated. This clinical situation should be considered an indication for conversion to open appendectomy. All appendiceal tumors, including the most benign-appearing adenomas, can result in diffuse peritoneal implantation. This is the first report of an appendiceal mucinous tumor resected by laparoscopy associated with subsequent diffuse peritoneal carcinomatosis. This patient presentation reaffirms that dissemination of cancer may be associated with laparoscopic resection of structures containing a malignancy.
