Extramedullary plasmacytoma with gastric and lymph node involvement: an immunological study.

A case of gastric and lymph node extramedullary plasmacytoma is reported in a young Algerian female. Treatment with cyclophosphamide was ineffective, but rubidazone, followed by a maintenance therapy with prednisone, procarbazine, and vinblastine induced a complete remission. Immunofluorescence studies and biosynthesis experiments in vitro showed that the tumor cells produced and secreted IgA-kappa molecules, whereas no monoclonal immunoglobulin could be found in the serum and gastric juice.

[Clinical, biological, histological, ultrastructural and therapeutic studies in one case (author's transl)].

The diagnosis of glucagonoma was made in a 51 year-old woman who suffered from a polymorphous dermatitis and an insulin-dependent diabetes mellitus. Denutrition was present and there was a previous history of thrombo-embolism. Immunoreactive plasma glucagon was constantly higher than 1 000 pg/ml (N less than 175). Plasma aminoacids were low. After angiographic confirmation, the tumour and part of its hepatic metastases were resected. The dermatitis disappeared soon after. Its recurrence required chemotherapy (successively mithramycin, streptozotocin, DTIC) and good clinical results were obtained. On histological examination, the cutaneous lesions consisted of an epidermal edema, and a bullous intra-epidermic detachment. The pancreatic tumour was of the trabecular type with a very important sclerosis. On electron microscopy, the tumoral cells, some with a syncitial aspect, contained granules of the D1 type. These granules are different from the typical glucagon granules. The clinical and biological features in this case are compared with those of the 41 cases of glucagonoma previously published.

Chronic non-specific ulcerative duodenojejunoileitis: report of four cases.

Four patients with chronic non-specific ulcerative duodenojejunoileitis (CNSUDJI) are reported. The clinical picture included abdominal pain, fever, and a malabsorption syndrome. Main rediological findings were diffuse narrowing of the jejunal loops with total effacement of the mucosal folds. Multiple peroral biopsies of the small intestine showed various degrees of mucosal abnormalities from total villous atrophy to normal villi, but ulcerations were diagnosed only by operative full thickness biopsies or resection of the small bowel. The ulcerative process was associated with well-documented coeliac disease in two patients: in one of them it occurred as a fatal complication involving also the colon, three years after the start of a gluten free diet, while the disease was in full clinical and histological remission. In the other case, coeliac disease was revealed by obstructive symptoms due to stenosing ulcerations; five months after surgical resection of the stenosis, institution of a gluten free diet induced a dramatic improvement. In the two other patients ulcerations were not associated with coeliac disease: one of them had a patchy villous atrophy and resisted a gluten free diet and total parenteral nutrition; she was improved by and dependent upon steroids but finally died. The last patient had normal villous height; ulcerations were located exclusively along the mesenteric border of the small bowel; he had a low-grade protracted evolution resisting any form of therapy and developed a peripheral neuropathy of unknown aetiology. On the basis of our cases and of a review of the literature the discussion focuses on the difficulty in diagnosing CNSUDJI, its relationship with coeliac disease, and its management and prognosis.
