Gastrointestinal symptoms were present at the time of diagnosis in 81 (76%) of 107 patients with coeliac disease: 56% had diarrhoea/steatorrhoea, 32.7% abdominal pain and 15% constipation. Gastrointestinal symptoms were commonest in young adults (20-39 years) and less frequent in children (0-19 years). Anaemia, low serum levels of folic acid, albumin and calcium, and raised serum alkaline phosphatase may be of help in raising the index of diagnostic suspicion, but in over half of our patients with clinically and histologically active disease these values were within normal limits. In patients adhering to a gluten free diet remission of symptoms correlated well with histological response; the continuation of symptoms indicated a higher incidence of histological abnormality. No patient not complying to the diet had normal histology on repeat biopsy. Five patients died over the ten year period, one from a small bowel lymphoma.

Primary small intestinal lymphoma (PSIL) represents a heterogenous group of disorders with variable clinical and pathologic features and a characteristic age, socioeconomic, and geographic distribution. In developed countries, PSIL usually occurs as a localized ileal tumor, shows a bimodal age distribution, and most frequently presents with abdominal pain and obstructive symptoms. Histologically, most of these tumors are diffuse histiocytic, lymphocytic, or undifferentiated lymphomas. Other variants of PSIL, collectively referred to as immunoproliferative small intestinal disease, occur most often among young patients of poor socioeconomic status in Third World countries, mostly in the Middle East and Mediterranean area. They are characterized by involvement of long loops of the upper small intestine and commonly present with abdominal pain, diarrhea, malabsorption, and clubbing of the fingers. A subgroup of these patients shows a serological abnormality with the appearance of part of the alpha heavy chain of IgA in the serum. Histologically, the lesion appears as a dense diffuse lymphoplasmacytic infiltrate of the mucosa of the upper jejenum or duodenum. A form of malignant lymphoma of true histiocytic origin complicates long-standing celiac disease. The contrasting clinical, epidemiological, histopathological, and immunological features of these variants of PSIL raise interesting questions about the pathogenesis of small bowel lymphoma.

Small bowel lymphomas account for 20 to 40% of primary gut lymphomas in Western populations and are among the most common malignant tumours of the small bowel. We studied 119 cases of primary small bowel lymphoma presenting over 4 decades. Two thirds of the patients were men with a peak age incidence in the 7th decade. Common presenting features included abdominal pain, weight loss, small bowel obstruction, and acute abdomen. Tumours were classified using the Kiel European Association for Haematopathology Geneva Workshop scheme and phenotyped on paraffin sections; 66% were B cells, and 34% were T cell. In all cases, the antibodies L26 and polyclonal CD3 reliably distinguished between B- and T-cell tumours. Of the B-cell lymphomas, 62% were diffuse high grade, 20% were low-grade lymphomas of mucosa-associated lymphoid tissue, 11% had both low- and high-grade components, and 7% were other low-grade types. Of the T-cell lymphomas, 83% were high grade, and 49% were enteropathy associated. Most T-cell lymphomas were ulcerated plaques or strictures in the proximal small bowel; B-cell lymphomas tended to be annular or polypoid masses in the distal and terminal ileum. Survival data showed that low-grade B-cell lymphomas had the best outcome and T-cell lymphomas the worst. Adverse prognostic features included perforation, high-grade histology, multiple tumours and advanced stage.

Lymphoproliferative disorder (LPD) is a well recognized complication of solid organ transplantation. It is associated with Epstein-Barr virus (EBV) infection and is often a fatal complication of immunosuppression. We report a 2.5-year-old boy who developed LPD presenting as small bowel lymphoma after liver transplantation. The patient had intermittent fever after transplantation and reactivation of latent EBV infection was documented by pre- and posttransplant serologic tests. About 5 months after his liver transplantation, the patient had sudden onset of abdominal pain and emergency laparotomy was performed for peritonitis. He proved to have multiple small bowel perforations caused by B cell lymphoma and died of multiple organ failure 9 days after operation, despite aggressive treatment and stopping immunosuppressive agents. We conclude that prevention of overimmunosuppression in pediatric recipients after liver transplantation and early detection and treatment of LPD are important to decrease this often-fatal complication.

Small intestinal malignancies are rare and may have a delayed presentation owing to insidious growth. We have reviewed the case notes of 25 patients presenting with primary small bowel tumours over a 10-year period. Abdominal pain, weight loss and vomiting were the most common symptoms. The median duration of symptoms was 6 months. Physical examination was normal in 24% of patients. An abdominal mass was present in 46% of cases. Emergency laparotomy was undertaken in 28% of patients. Lymphomas were identified in 72% and adenocarcinomas were present in 16%. The predominance of small bowel lymphoma is an unusual finding and may be related to the high incidence of coeliac disease in the region. The median survival in the lymphoma group was 36 months, which compares favourably with reported series.

Sclerosing mesenteritis is a rare inflammatory disease of the bowel mesentery of unknown aetiology. It poses a diagnostic challenge for clinicians, as it can be mistaken for malignancy. We report a case of sclerosing mesenteritis initially presented with abdominal pain, tender abdominal mass and small bowel obstruction. Emergency laparotomy revealed fibrous thickening of the small bowel mesentery mimicking small bowel lymphoma. An ileo-ileal bypass procedure was performed. Six months later, the patient developed retroperitoneal fibrosis, manifesting as bilateral obstructive uropathy. Our case is unique, as it describes retroperitoneal fibrosis developing in a patient with small bowel retractile mesenteritis, with no evidence of colonic or other anatomical involvement. Furthermore, the patient had no risk factors for this condition. We conclude that the presence of sclerosing mesenteritis should cue clinicians to search for other coexisting inflammatory disorders that can have serious sequelae.
