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.

Twenty two consecutive cases of adult intussusception managed between January 1990 and December 1998 at Jos University Teaching Hospital formed the basis of this study. Thirteen (59.1%) of the patients were males and 9(40.9%) females, with a male to female ratio of 1:4:1 and a mean age of 49.6 years. Most patients were referred late to our service as a result of poor index of suspicion and misdiagnosis. Laparotomy was done in all the cases and in 5(22.7%) patients no cause could be found, but in the remaining 17(77.3%) definite causes were identified which were mainly polyps in 7(31.8%) patients and colonic malignancies in 4(18%). The ileocolic intussusception was the commonest variety. Sixteen (72.7%) patients had bowel resection for colonic carcinoma, gangrenous bowel and irreducibility of the intussusception while manual reduction was successful in the other 6(27.3%) patients. The morbidity rate was 22.7% and the complications were wound infection and adhesive intestinal obstruction. Two deaths were recorded with a mortality rate of 9.1%. The pattern of adult intussusception as seen in the western world was observed in this tropical highland.

Puetz-Jegher's syndrome is an autosomal dominant hereditary disease, which is characterized by hamartomatous polyposis and mucocutaneous pigmentation mainly over the circum-oral region. Patients with Peutz-Jeghers syndrome seek medical attention whenever there are complications such as intussusception, bleeding from the polyps, etc. Occasionally, gastrointestinal tract malignancies have been reported in Peutz-Jeghers syndrome. In this paper, we report a patient with Peutz-Jeghers syndrome who had multiple complications and polyposis involving the appendix, because involvement of the appendix is extremely rare in Peutz-Jeghers syndrome.

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.

Endoscopic surgery has been established in various surgical conditions in children and infants for the past 10 years after pioneering work by experts specializing in pediatric endosurgery. These include pull-through for Hirschsprung's disease and anorectal malformations, pyloromyotomy, hernia repair, and endoscopic surgery for malignancies, malrotation, intussusception, etc. Laparoscopic pull-through is now accepted as a standard modality for the treatment of Hirschsprung's disease. Advanced endoscopic procedures such as esophageal atresia repair or fetal tracheal occlusion have also been performed. An efficient system for training is needed to compensate for the small number of patients and varieties of specific illness in children.

Clinical manifestations and imaging findings of mantle cell lymphoma involving gastrointestinal tract were evaluated. The subjects were 7 cases of mantle cell lymphoma involving the gastrointestinal tract. All cases were pathologically confirmed in our hospital during the period from April 1994 to July 2000. Five patients were male and 2 were female, and their age ranged from 49 to 63 years (average 57.4). The objectives were: 1) characteristics and distribution of multiple polyposis, 2) presence, location and enhancement pattern of bowel wall thickening or mass formation, 3) presence of splenomegaly, 4) presence and location of abdominal lymph node enlargement, 5) involved extra-abdominal organs, 6) combined cancer and location, and 7) other findings. All mantle cell lymphomas occurred in elderly persons, over 40 years, and most showed multiple polyposis (6/7), bowel wall thickening or mass formation (6/7), lymph node enlargements (6/7) and extra- abdominal involvement (5/7). All cases of polyposis involved the small bowel and colon, and the size of the polyps ranged from 0.1-4.0cm. Four of 6 patients showed combined sessile and polypoid polyps, while the other 2 showed only sessile polyps. Most of or some of the polyps in 3 patients showed small central ulcerations. Most of the patients (5/6) showed an uncountable number of polyps. Polyposis was predominant in the rectum, ascending colon, rather than other sections in the colon, and the ileum were almost always involved by polyposis. Bowel wall thickening or mass formation developed exclusively in the ascending colon, rectum or ileum. Extra- abdominal involvement developed either simultaneously or nonconcurrently with gastrointestinal involvement. Some of patients showed splenomegaly (3/7), appendiceal enlargement (2/7), and intussusception (1/7), and some had associated adenocarcinomas (3/7).

In two adult patients, a 74-year-old woman and a 84-year-old man, who suffered from vague abdominal complaints, an intussusception was diagnosed by CT. Surgical resection of the affected bowel parts was successful. Intussusception is usually seen in children; in adults it is a rare condition. Adult patients mostly complain about vague abdominal pain only. Physical examination, laboratory investigations and plain abdominal X-rays often don't give any additional information. In such patients it is advised to perform CT of the abdomen at an early stage. CT may show a so-called 'target sign' which is characteristic of an intussusception. In addition it can provide information about the possible causes of the intussusception, most commonly a malignant tumour in adults. During laparotomy one should not attempt to reduce the intussusception because of the risk of tumour spill. In this clinical review, we present two adult patients with unexplained abdominal complaints due to intussusception, caused by malignancy.

We report the case of a patient with von Recklinghausen's disease, who was admitted with a diagnosis of acute abdomen due to small bowel neurofibromatosis. The patient was submitted to an abdominal CT scan that showed a homogeneous round lesion, with a regular margin, probably belonging to the small bowel and with the appearance of a benign lesion that probably caused an intestinal intussusception. The patient was submitted to a surgical procedure that mainly consisted in multiple small bowel resections. The histopathological examination confirmed the benign nature of the lesions. About one third of patients affected by von Recklinghausen's disease present involvement of the bowel, but only 5% of them are symptomatic. The intestinal tumours are usually neurofibromas and are mainly localized in the jejunum. However, there have also been reports of stromal, nervous and endocrine tumours and even other tumours not belonging to these categories, including adenocarcinoma. The overall incidence of intestinal malignancy in patients with von Reckilnghausen's disease is about 10%. The surgical operation, as well as the histopathological and immunochemical examination of the intestinal lesions are of crucial importance for the treatment of the complications of intestinal neurofibromatosis and for the treatment and diagnosis of malignancy.

Intussusception typically occurs in childhood, presenting with a well-known medical history and clinical symptoms. Pathologically, a "leading point" may be attributed to lymphadenomatosis, polyps, or a tumour. In older patients and adolescents, the diagnosis can be complicated due to the lower incidence and variable subacute symptoms. We report on an 18-year-old patient with increasing abdominal discomfort over several weeks. External diagnostics showed no pathological signs or were misinterpreted as a malfunction of intestinal motility. The patient experienced increasing colics, recurrent vomiting, dehydration and weight loss. Finally he was transferred to our paediatric surgical department and laparotomy had to be performed for the clinical and radiological signs of an ileus. An ileoilealic intussusception was found, caused by a small bowel tumour, which almost completely obstructed the intestinal lumen. It was resected and bowel continuity was re-established. Histopathology revealed a very rare, highly malignant mesenchymal Ewing sarcoma, infiltrating the complete bowel wall. After the postoperative course, the patient was transferred to our oncological department for chemotherapy. In older children or young adults, intestinal malignancies are extremely rare. Nevertheless, if these patients suffer from unspecific complaints of chronic intestinal obstruction, a tumour must be ruled out. A Ewing sarcoma may be responsible for an intussusception.

The case of a 55-year-old woman with a pedunculate adenoma of the papilla of Vater is presented. Diagnostic imaging modalities including ultrasonography, CT scan, magnetic resonance of cholangiopancreatography, simultaneous duodenography and cholangiography, and angiography showed a giant tumor protruding intraluminally and moving forward in the duodenum by peristalsis. It had a duodenal intussusception-like appearance, with remarkable left-lower deviation of the common bile duct and major pancreatic duct in the papilla of Vater as far as the left side of the aorta. Episodes of jaundice or ileus were absent, probably because the tumor was mobile in the duodenum. As biopsy specimens showed no malignancy and intraductal ultrasonography in the common bile duct revealed no intraductal invasion of the tumor in the papilla of Vater, the patient underwent transduodenal papillectomy with papilloplasty with pancreatic ductoplasty. Pathological diagnosis of consecutive specimens was a papillary adenoma with moderate atypia and occasional tubular structure. There seems to be an exceptional subtype of the tumor in the papilla of Vater, like this case, demonstrating the duodenal intussusception-like appearance without prominent clinical symptoms.
