From our experience of malignant lymphoma in the large intestine and reviewing the Japanese literature, it might be concluded that this particular lesion was extremely rare, and was found predominantly in the right side of the colon. In contrast to the other malignant neoplasms in the large intestine, malignant lymphoma was found fairly often in children, which was accompanied by intussusception not infrequently.

An unusual case of lymphoma is presented in which small bowel intussusception due to a lymphomatous nodule caused an acute abdomen, requiring small bowel resection. Four weeks later a second intussusception caused intestinal obstruction, necessitating a second laparotomy and bowel resection. The high incidence of malignant tumor in adult cases leads us to recommend primary resection without manual reduction in all but rectosigmoid and selected small bowel cases.

Clinico-pathologic analysis of 60 patients with primary malignant lymphoma of the small intestine and mesentery is presented. It occurs mainly in the adult. Both of these two tumors were first presented by abdominal pain and mass. Secondary anemia was common. They were complicated by intestinal obstruction, perforation or intussusception. The prognosis was aggravated by a large tumor mass, advanced stage and pathology of diffuse large cell subtype. Combined surgery, chemotherapy and radiotherapy were effective.

Primary neoplasms of the small bowel are unusual and constitute 1-5% of all gastrointestinal tract neoplasms. Preoperative diagnostic difficulties, frequent dissemination at the time of the diagnosis, and poor prognosis are characteristic of this pathology. During a period of 26 years we treated 61 patients with tumors of the small bowel, 44 malignant and 18 benign (1 patient had both). The most common symptoms were abdominal pain (62%), weight loss (41%), and gastro-intestinal bleeding (31%). More than half of the patients were treated as emergencies and among the remaining, the most useful diagnostic test was the small intestinal barium study. Seventeen patients were operated on for intestinal obstruction, 6 of them due to intussusception of the tumor, while 8 other patients presented with perforation and 7 with massive gastrointestinal bleeding. Leiomyoma was the most frequent benign lesion. Among malignancies lymphoma was encountered in 38.6%, followed by adenocarcinoma (29.6%) and leiomyosarcoma (22.8%). Lymphoma was predominant among Sephardic Jews. Curative procedures were attempted in all but one of the benign cases and in 21 of the malignant cases. At the time of surgery metastases were present in 23 patients. The postoperative mortality was high (20% and 14% in the benign and malignant groups, respectively) most probably due to the high incidence of emergency surgery in a high risk population. The prognosis of the malignant tumors was poor with a 5-year survival of 18%. Their disappointing course seems to be related to late diagnosis because of nonspecific symptoms and difficulty in bringing the tumor to the fore. Hopefully, a greater awareness will lead to an earlier diagnosis and improve the prognosis.

Twenty-seven cases of small bowel tumour confirmed surgically and pathologically have been studied. The sonographic appearances are described as well as a method of ultrasound detection following water ingestion. Tumours were classified into: (i) intraluminal tumours (duodenal adenocarcinoma n = 5; distal ileal lipoma with intussusception, n = 1; (ii) intramural tumours (proximal jejunal adenocarcinoma, n = 2; jejuno-ileal lymphoma, n = 5; (iii) extraluminal tumours (duodenal leiomyosarcoma, n = 2; neurilemmoma, n = 1; jejuno-ileal leiomyoma, n = 4; leiomyosarcoma, n = 6; subserosal lymphangioma, n = 1). Observing the lesion intermittently over a period of 1 h after water ingestion improves the localization of tumours within the small bowel.

Eighteen patients with 20 primary lesions of small intestinal lymphoma of the 'Western' type were examined to determine the double-contrast radiographic features of the disease with pathological correlation. The radiographic appearances on double-contrast study were divided into five groups: polypoid (3 lesions), stricturing (6), non-stricturing (3), aneurysmal (3), and intussusception (5). In the first four groups, ulceration, signs of submucosal tumour, and displacement of adjacent loops were frequent. Two early lesions confined to the submucosal layer were also seen. There was a close association between the radiographic appearance and macroscopic findings of the resected specimens, including the cross section of the tumour, but no correlation with the cell type. These results indicate that the double-contrast study accurately reflects the morphological changes of primary small intestinal lymphoma.

Lead point lesions are very rarely suspected during ultrasound (US) investigation of intussusception. We report a case of idiopathic intussusception where US suggested a cystic lead point. At operation there was no structural abnormality but fluid was noted to be trapped within intussuscepted mesentery. The incidence of 'non-idiopathic' or 'secondary' intussusception is 5-6% with Meckles diverticulum being numerically the most important single entity. The lead point is only rarely identified on ultrasound. A large Chinese series of 377 cases of diagnosis and reduction of paediatric intussusception under US control [1] makes no mention of ultrasonic identification of a secondary cause in any of their cases. A European series of 145 cases [2] noted a causative lesion in 8 (5.6%), of which 2 (lymphoma, intestinal duplication) were identified during the ultrasound study. Adamsbaum [3] recently published a case of an enterogenous cyst as a lead point identified on ultrasound. We present a case with very similar ultrasonic features but which at operation was found to represent fluid trapped within the intussuscepted mesentery rather than a true cystic lead point.

Ultrasonography offers direct imaging of the bowel wall and allows dynamic evaluation of peristalsis. It helps to differentiate eosinophilic gastroenteritis from regional enteritis and lymphoma, displays a typical appearance in intussusception and is quite specific in the afferent loop syndrome, closed-loop obstruction and lymphedema. It may be helpful in ischemia of the bowel and in the evaluation of acute appendicitis.

The adult intussusception is rare. Here, we describe a case of an adult patient with ileocolic intussusception secondary to a recurrent lymphoma of the terminal ileum. The patient was a 42-year-old female, who had a history of the subtotal gastrectomy because of the primary gastric lymphoma. Eight months after the operation, she had a relapse in the abdomen and received the combination chemotherapy. She acquired the complete remission, but six months after the completion of the chemotherapy, she suffered from the right lower abdominal pain and diarrhea. Physical examination revealed a soft mass with tenderness in the right iliac fossa. Barium studies and abdominal computed tomography showed an ileocolic intussusception. At laparotomy, a 4.5 cm polypoid tumor was found in the terminal ileum and it passed through the ileocaecal valve to form an intussusception. Histologic examination disclosed the follicular lymphoma of medium-sized cell type. So far as we are aware, this is the first report of an adult patient with intussusception secondary to a lymphoma in Japan.
