Immunoproliferative small intestinal disease (IPS~D) is a prevalent, debilitating illness in many developing countries particularly Middle East and the. Immunoproliferative small intestinal disease (IPSID) is a special variant of, extranodal marginal zone B-cell lymphoma, which affects the small intestine. In early.

Responses, however, are usually transient. Plasma cells are CD20 negative and CD positive. No light chain restriction was seen on IHC. Immunoproliferative small intestinal disease IPSIDa term adopted xmall WHO inis a variant of extranodal marginal zone lymphoma of mucosa associated lymphoid tissue MALT in which defective heavy chains are secreted. The diffuse immunoproliferation inthe intestinal wall, in response to bacterial and parasitic inrestinal, increases the chances of random malignant transformation of rapidly proliferating cells by DNA-reactive agents such as carcinogens in food or other environmental factors.

Immunoproliferative small intestinal disease (IPSID): a model for mature B-cell neoplasms.

Cytogenetic studies demonstrated clonal rearrangements involving predominantly the heavy and light chain genes, including t 9;14 translocation involving the PAX5 gene. Support Center Support Center. IgA was focally expressed Figure 3 and positive staining for CD was noted in the plasma cells Figure 4. Common sites of involvement are small intestine duodenum and jejunum and mesenteric lymph nodes.

JPS1D typically presents in an adolescent oryoung male with chrome diarrhoea, malabsorption syndrome, weight loss, clubbing, abdominal pain and occasionally abdominal mass. Subsequently most cases are characterized by a loss of ability to synthesize light chains. In the past, early phase of IPSID was thought to be inflammatory, but evidence of clonality indicates the neoplastic nature of this process, despite response to antibiotics.



The disease usually effects the duodenum and proximal jejunum but ileal and pan- intestinal involvement may also occur The encoding gene sequence reveals a deletion of V region and parts of C H 1 domain. Our expenence with stage C disease confirms these observations Immunoproliferative small intestinal disease and primary small intestinal lymphoma: Although equal sex distribution has been suggested, a male prepoaderance and no racial predilection are quite characteristic Primary upper small-intestinal, lymphoma: The M-component typed as IgA denoted by the band seen in the IgA lanebut without a corresponding light chain only faint polyclonal pattern was seen in kappa and lambda lanes.

Cytogenetic abnormalities have been reported in rare single cases.

Immunohistochemical ddisease that show plasma cells expressing only a heavy chains confirm the diagnosis. A study of 43 cases from a pathology department in Israel. The associated findings include frequent gmwth retardation, clubbing of fmgers and toes, abdominal pain and occasionally intesginal.

Hence, it appears that IPSID passes progressively through phases of pre-malignant lymphomatous change to low grade malignancy to highly malignant immunoblastic lymphoma. More dysplastic cells are usually present farthest away from the surface mucosa. Treatment of Alpha chain disease. This correlates with an abnormally short alpha-chain messenger RNA produced smalll these patients.

Internal deletions in the alpha heavy chain gene are present that result in the expression of a defective heavy chain protein that cannot bind light chains to form a complete immunoglobulin molecule.

High-dose aggressive combination chemotherapy has been demonstrated to offer no advantage Clinicopathological features and management of immunoproliferative small intestinal disease and primary small intestinal lymphoma in Pakistan.


Immunoproliferative small intestinal disease (IPSID): a model for mature B-cell neoplasms.

The deletion involves the VH region variable region of immunoglobulin heavy chain gene and CHl region first segment, constant region of immunoglobulin heavy chain gene. Patients with stage A disease are often initially treated with antibiotics. Clinicopathological features and relationship to so-calledMediterraneanlymphoma. Immunohistochemically cells express monoclonal cytoplasmic alpha chains without light chains.

It has been hypothesized that recurrent intestinal infections in patients living in the endemic areas are carcinogenic. Serum electrophoresis with immunofixation: Primaiy small intestinal lymphoma in the endemic countries is commonly associated with IPSID and hence has been called Mediterranean lymphoma Immunoproliferative small intestinal disease IPSID is an uncommon disorder in the developed countries.

Two wedge biopsy specimens from the ends of the duodenum and ilium respectively. Most untreated IPSID patients progress to lymphoplasmacytic and immunoblastic lymphoma invading the intestinal wall and mesenteric lymph nodes, and may metastasize to a distant organ.

Occasionally, when diagnosis cannot be established on endoscopic biopsy, diagnostic and staging lapamtomy may be indicated During the early phase, the process is potentially reversible if antigenic stimulus can be removed as reflected by prolonged remission induced by the antibiotic therapy
