A case of acute gangrenous appendicitis with perforation caused by metastatic small cell carcinoma of the lung in a 65 year old man is reported. The manifestation of appendicitis occurred more than 4 years after the diagnosis of the bronchogenic carcinoma. With longer survival of patients with disseminated tumors it is probable that new manifestations of those malignancies will be discovered. Acute appendicitis due to metastasis from a distant neoplasm should be considered in the differential diagnosis of right lower abdominal pain in the oncology patient.

Mucinous cystadenocarcinoma in the appendix is uncommon. An anomaly in the rotation of the intestine is also uncommon in adults. We herein report a case of mucinous cystadenocarcinoma in the appendix in a patient with nonrotation. To the best of our knowledge, this is the first report of appendiceal carcinoma in a patient with an anomaly of intestinal rotation. A 76-year-old woman was admitted to our hospital with left low abdominal pain. Physical examination revealed tenderness with muscle rigidity in the left lower quadrant. The patient was diagnosed to have intussusception by computed tomography and ultrasonography. An emergency operation showed nonrotation and the top of the appendix situated in the left iliac fossa. An appendectomy was performed because of gangrenous acute appendicitis. However, the cut surface of the appendix showed a mucocele measuring 4 x 4 cm in size. It was diagnosed to be mucinous cystadenocarcinoma histopathologically. A right hemicolectomy with lymph node dissection was performed, and no remaining cancer cells or lymph node metastases were found in the resected specimen pathologically. The patient had an uneventful postoperative course. No signs of recurrence have been observed for 23 months since her last operation.

Adult intussusception is very rare. We report 2 unusual cases, a 58-year-old man with a transverse colo-colonic intussusception caused by a malignant sessile polyp that also had an asymptomatic synchronous neoplasm of the kidney, and an 18-year-old female with an ileocecolic intussusception caused by acute appendicitis. This report stresses the point that intussusception in adults may represent an underlying malignancy. The age of the patient and the anatomic location of the intussusception provide significant input as to the etiology and hence the most appropriate surgical procedure.

We report the case of a 12-year-old European boy presenting with an appendicular Burkitt's lymphoma. He complained of right lower abdominal pain mimicking acute appendicitis. Ultrasonography and abdominal CT showed an appendicular mass which features were strongly suspicious for malignancy. This case emphasizes the importance of medical imaging to characterize appendicular lesions and to select the surgical technique. Accurate diagnosis was obtained histologically on resected specimen.

Diagnostic laparoscopy began in a surgical unit in a developing country in 1972. The developers of this technique aimed to hasten diagnosis, reduce patient distress, and improve bed utilization in an overcrowded teaching hospital wherein simple investigations such as x-rays took weeks to materialize. Over a period of 18 years reaching to 1990, 3,200 diagnostic laparoscopies were performed on adults under local anesthesia with no mortality, a complication rate of 0.09%, an 84% diagnosis rate, and 74% undergoing histologic biopsies targeting a wide spectrum of pathology. The equipment cost spread out over the 3,200 patients works out to 30 rupees (0.60 dollar) per patient. With the availability of noninvasive diagnostic aids such as ultrasound, computed tomography, and magnetic resonance imaging used US, CT, MRI under the control of target biopsy, the role of diagnostic laparoscopy has altered. Since 1990, clinicians have had the sophistication of the video camera and the pneumoperitoneum insufflator. Diagnostic laparoscopy is used for the evaluation of liver and peritoneal pathology, abdominal tuberculosis, malignancy, acute abdomen, and abdominal trauma. It often is a prelude to laparoscopic treatment of the underlying pathology, specifically in cases of acute appendicitis.

Since the middle to the end of the 80 s, the sonographic detection of diverticulitis has been increasingly improved. In a paper including a larger number of patients published in 1992, W. B. Schwerk demonstrated a high sensitivity and specificity. The detection of diverticulitis was the final entry into the chapter of acute abdominal sonography, after the diagnosis of gastrointestinal perforation, acute appendicitis and ureterolithiasis had been achieved with high reliability. Until then, diverticulitis was a classic surgical disease and a contrast enema with water-soluble contrast medium the diagnostic method of choice. Invariably, the radiologist added the well known comment: Cancer of the sigmoid colon cannot be excluded with certainty. What has changed in the 12 years after Schwerk's publication? Many internists practising sonography have discovered the sonographic diagnosis of this condition and, depending on the severity, treat the less complicated cases with intravenous antibiotics and parental nutrition or with oral antibiotics and low-ballast diet. Soon, abscesses were healed with sonographically guided aspiration and drainage. For a long time, the older generation of surgeons stayed with contrast enemas and prolonged parenteral therapy and, in case of complications, surgical interventions, though surgeons early recognized the diagnostic contribution of sonography. Influenced by radiologists and the Anglo-American literature, surgeons increasingly used computed tomography (CT) as standard method for the initial diagnostic work-up for the last five to eight years. A physician dedicated to gastrointestinal sonography cannot accept this approach, in particular, since sonography is easy and reliable, provides a reasonable differential diagnosis and was found to help the surgeons. An exception is the deep-seated diverticulitis in the sometimes barely accessible distal sigmoid colon. Furthermore, an experienced clinician will anyhow proceed to CT in any unexplained discrepancy between clinical and sonographic findings. It reflects the high value given to sonography if our surgical colleagues use this diagnostic method in the primary diagnosis of acute diverticulitis and achieve results that are as good as the results of the expensive and by all criteria more elaborate CT. The extended application of ultrasound for the omentum and in necrotic epiploic appendagitis should be mentioned here as well. Altogether, CT can be easily refrained from in 80 % to 90 % of cases with suspected diverticulitis. In view of the DRG era, this is an important argument, and emphasizes the economic role of sonography, the necessity of correct coding of sonographic procedures and the need of more sonographic training. Only quality will increase the acceptance of sonography as diagnostic tool as repeatedly demanded and presented in this journal. If this fails, it is highly likely that the diagnostic potential of sonography will remain unexploited or, under the best of circumstances, rediscovered after a 5-year expiration date in a new literature search in 10 years.

The authors describe a case of acute appendicitis associated "serrated" adenoma (SA). to the histological finding of a SA is a colorectal pre-cancerous lesion which presents the morphological and architectural characteristics of hyperplasic polyps, combined with aspects of adenomatous dysplasia. SA can eventually evolve into a malignant cancer, similarly to classic adenomatous polyps. Clinical and pathological aspects of this lesion are hereby analysed, with respect to recent Literature data.

Malignant lymphoma comprises 1-4% of the malignant neoplasm of the gastrointestinal tract. Appendiceal lymphomas are extremely rare, reported in 0.015 percent of all gastrointestinal lymphomas. This is a report of a case of localized malignant lymphoma of the appendix associated with the histological features of acute inflammation that presented clinically as acute appendicitis. A three years follow-up after appendectomy alone did not show any evidence of recurrent disease. This case report emphasizes the importance of routine histology examination of the appendectomy specimen.

Mucocele is an uncommon pathology of the vermiform appendix that can be confused with acute appendicitis. We present a case of an appendiceal mucocele associated with subacute, intermittent right lower quadrant discomfort. The diagnosis of appendiceal mucocele is an important one in that it can be associated with malignancies and other serious gastrointestinal, ovarian, and urological complications.

Primary malignant epithelial tumors of the appendix are uncommon. The most common presentation of appendiceal malignancy is right lower abdominal pain suggestive of acute appendicitis. Presentation caused by loco-regional spread with involvement of neighboring organs is rare. We present the case of a 48-year-old woman with an appendiceal malignancy who presented with symptoms and signs suggestive of complicated diverticular disease with an enterovaginal fistula. From a review of the literature, this is the first report of an appendiceal malignancy presenting in this manner.
