1/91. Granulocytic sarcoma (chloroma) of the small intestine.Granulocytic sarcoma or Chloroma may develop before, at the time or after presentation of acute myeloid leukemia. We report the case of a 66-year old man presenting with intermittent abdominal pain during one month before developing a peritonitis due to perforation of small bowel followed by irreversible shock and death. Nearly the entire length of small bowel and bone marrow were infiltrated by giant promyelocytic cells. Abnormal circulating cells were never discovered. The literature is briefly reviewed.- - - - - - - - - - ranking = 1keywords = abdominal pain, pain (Clic here for more details about this article) |
2/91. intussusception in the older child- suspect lymphosarcoma.Examination of the records of 378 children with intussusception at our institution revealed that 29 cases were caused by an identifiable intestinal lesion. A Meckel's diverticulum was the causative agent in 21 children, all of whom were under 2 yr of age. A previously undiagnosed ileal lymphosarcoma produced the intussusception in six other children, all between 6 1/2 and 9 yr of age. Our experience indicates that any child over 6 yr of age with the clinical findings of colicky abdominal pain, bloody stools, and a palpable mass plus the radiographic evidence of intussusception must be considered to have ileal lymphosarcoma until proven otherwise. Hydrostatic reduction of the intussusception must be accompanied by extensive small bowel reflux of barium in order to effectively rule out a small intestinal lesion. If this is not accomplished, surgery should be planned with the suspicion that a malignancy may be present. If this suspicion is confirmed by frozen section, the operation procedure should include wide surgical excision of the lesion along with the regional lymph nodes.- - - - - - - - - - ranking = 1keywords = abdominal pain, pain (Clic here for more details about this article) |
3/91. Bowel perforation during chemotherapy for non-hodgkin's lymphoma.Bowel perforation in patients with primary malignant lymphoma usually occurs at the site of tumor. A 78 year-old man underwent chemotherapy for malignant lymphoma. He presented with abdominal pain. An emergency operation was performed under a diagnosis of panperitonitis. At laparotomy, an anal-side perforation approximately 20 cm from the Treiz ligament was observed. drainage and partial resection of the jejunum was performed. Histopathologic examination demonstrated that there was no characteristic finding of malignant lymphoma around the perforation site in the case. Perforation of the small intestine is one of the most critical complications during the chemotherapy for malignant lymphoma. In cases of chemotherapy for malignant lymphoma, especially systemic administration, we should keep in mind the possibility of perforation of the small intestine. Fortunately, emergency surgery saved the patient presented in this report. Early diagnosis and treatment are important to improve prognosis of bowel perforation in patients with primary malignant lymphoma.- - - - - - - - - - ranking = 1keywords = abdominal pain, pain (Clic here for more details about this article) |
4/91. Spontaneously relapsing clonal, mucosal cytotoxic T-cell lymphoproliferative disorder: case report and review of the literature.Primary T-cell lymphoma of the gastrointestinal tract is a rare and usually aggressive disorder that may be associated with celiac disease. The authors describe a unique case of a clonal proliferation of CD8 T cells involving the oral mucosa, ileum, and colon of a 35-year-old man that has regressed spontaneously and recurred numerous times over a 9-year period without treatment. The patient's symptoms were limited to occasional rectal bleeding and recurring painful oral ulcers. Within the intestine, these collections of small T cells induced minimal architectural distortions and did not show extensive epitheliotrophism. polymerase chain reaction and sequencing analyses revealed that the identical T-cell clone has been present for more than 9 years and in different mucosal locations in this patient. This may represent a unique T-cell lymphoproliferative process akin to a mucosal counterpart of lymphomatoid papulosis of the skin.- - - - - - - - - - ranking = 0.071098574828935keywords = pain (Clic here for more details about this article) |

6/91. Small bowel haemangioma with local lymph node involvement presenting as intussusception.Gastrointestinal haemangiomas make up 0.05% of all intestinal neoplasms. They are sometimes multiple and usually present with pain, bleeding, and obstruction. An associated haemangiomatous change in regional lymph nodes has not been reported previously. A woman of 21 years presented with abdominal pain and vomiting. Abdominal ultrasound and computed tomography scan showed a lower abdominal mass. laparotomy revealed a small bowel tumour causing an intussusception together with enlarged mesenteric lymph nodes. Pathological examination revealed a small bowel haemangioma with mesenteric node involvement. The pathogenesis of haemangiomatous involvement of lymph nodes is discussed. Hamartomatous change is the likely cause in this patient.- - - - - - - - - - ranking = 1.0710985748289keywords = abdominal pain, pain (Clic here for more details about this article) |
7/91. Multifocal epithelioid angiosarcoma of the small intestine.A 67-year-old man presented with weight loss, intermittent severe abdominal pain and melaena. Initial radiology (including abdominal ultrasonography), gastroscopy and colonoscopy did not demonstrate any lesions that could explain the complaints. Three weeks later, upper gastrointestinal and small-bowel barium studies revealed two areas in the small intestine with an abnormal mucosal pattern. Explorative laparotomy revealed three tumoral lesions. Three partial enterectomies were performed. Gross examination showed centrally depressed dark reddish tumoral lesions extending from the mucosa throughout the full thickness of the bowel wall (diameter varying between 1.6 cm and 2.2 cm). The tumours, composed of large, plump, polygonal cells showing little architectural differentiation, were mainly situated in submucosa and muscularis propria. The growth pattern appeared rather solid. The epithelioid cells showed pronounced nuclear pleomorphism and atypia with central large nucleoli. There were several small blood vessels with occasional anaplastic endothelial cells. Immunohistochemical staining demonstrated an intense expression of CD 31, CD 34, factor viii related antigen and keratin. This supported the diagnosis of an epithelioid angiosarcoma. The patient died 3 months after diagnosis. Tumours of the small intestine are very rare, and angiosarcomas of the small intestine are even more rare. Epithelioid variants have only been described in two patients and only one of these had a multifocal presentation. The prognosis is very poor. Because of the epithelioid growth pattern and the cytokeratin expression, these tumours may erroneously be diagnosed as a carcinoma.- - - - - - - - - - ranking = 1.0046196305829keywords = abdominal pain, pain, upper (Clic here for more details about this article) |
8/91. Diffuse small bowel involvement in malignant histiocytosis.The extremely unusual patient reported here had malignant histiocytosis with extensive gastrointestinal involvement. The presenting symptoms were those of a gastrointestinal disorder and barium studies of the upper gastrointestinal tract revealed an infiltrative process of the entire small bowel. A biopsy of the small bowel demonstrated abnormal malignant cells and the diagnosis of malignant histiocytosis was considered and confirmed at postmortem. strongyloidiasis, which was also found in this patient, may represent a hyperinfestation phenomenon due to altered host-parasite balance.- - - - - - - - - - ranking = 0.0046196305828873keywords = upper (Clic here for more details about this article) |
9/91. Enteroscopy as a tool for diagnosing gastrointestinal bleeding requiring blood transfusion.iron-deficiency anemia secondary to gastrointestinal blood loss is a common cause of hospitalization. In many cases, the bleeding site cannot be defined despite thorough routine examination of the gastrointestinal tract. The aim of this study was to evaluate push enteroscopy as a diagnostic tool in patients with severe anemia, secondary to recurrent gastrointestinal bleeding, that required management by transfusion. Thirty-five consecutive push enteroscopy investigations were performed in 1998 and 1999 on 25 patients (15 men, 10 women). Mean age was 57 /- 16 years (range, 33-83). All patients had received blood transfusions because of pronounced anemia secondary to gastrointestinal bleeding. Before push enteroscopy, all patients had been investigated with esophagogastroduodenoscopy, colonoscopy, and small-bowel radiography using the double contrast technique; no bleeding site was found. In addition, 10 of 25 patients had been investigated beforehand with 99mTc-labelled red blood cell scintigraphy, and 5 of 25 with scintigraphy for meckel diverticulum. Two patients were also investigated with angiography before the push enteroscopy, and in six patients an additional total intraoperative enteroscopy was performed, preceded by a new colonoscopy, esophagogastroduodenoscopy, and push enteroscopy. A bleeding site was disclosed in 15 of 25 (60%) patients. In 7 of 25 patients (28%) the bleeding site was found in the stomach or esophagus. even though the patients had undergone one or two esophagogastroduodenoscopies earlier with normal findings. Total intraoperative enteroscopy identified a bleeding site in four of six (67%) patients studied. Two patients had bleeding hemangiomas that were resected surgically. Two patients had small intestinal adenomas, one with adenocarcinoma in situ. Push enteroscopy performed with an overtube inserted under fluoroscopic guidance is an important diagnostic tool in patients in whom conventional examinations do not disclose bleeding sites. Interestingly, 28% of patients had bleeding within reach of the gastroscope, indicating that a new upper endoscopy should be recommended before push enteroscopy is performed. When no positive findings are seen on push enteroscopy and the patient is affected by severe, recurrent iron-deficiency anemia, total intraoperative enteroscopy should be considered.- - - - - - - - - - ranking = 0.0046196305828873keywords = upper (Clic here for more details about this article) |
10/91. Intestinal metastasis causing intussusception in a patient treated for osteosarcoma with history of multiple metastases: a case report.Intestinal intussusception caused by metastatic tumors is a very rare condition. Preoperative diagnosis is not easy because of the condition's rarity and because of mild abdominal physical presentation. We report on a patient with osteosarcoma who suffered from abdominal pain and emesis during the period of autologous peripheral blood stem cell transplantation. He had undergone tumor excision and radiotherapy several times prior to autologous peripheral blood stem cell transplantation because of multiple metastases. Intestinal metastasis was suspected initially by computed tomographic scan and sonogram and was proved by surgical resection and pathological findings. Clinicians caring for pediatric patients with osteosarcoma with a history of multiple metastases should consider the possibility of intestinal metastases when equivocal abdominal symptoms develop after intensive chemotherapy.- - - - - - - - - - ranking = 1keywords = abdominal pain, pain (Clic here for more details about this article) |
