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.

Natural history ofaipha-chain disease and the so-called Mediterranean lymphoma, recent results. No corresponding light chain identified. Pathological study of alpha-chain disease with special emphasis on evolution. Pathologic hallmark of IPSID is presence of diffuse and intense infiltration of the small intestinal mucosa and mesenteric lymph nodes with lymphoplasmacytic cells The diffuse immunoproliferation inthe intestinal wall, in response to bacterial and parasitic antigens, increases the chances iintestinal random malignant transformation of rapidly proliferating cells by DNA-reactive agents such as carcinogens in food or other environmental factors.

Immunoproliferative small intestine disease (IPSID) / Mediterranean lymphoma

Most often, these studies will suggest malabsorption syndrome 28, A study of intetsinal cases from a pathology department in Israel. It canbeofbothsecretoiy ornon-secretozy type. This may at times be responsible for the delay in diagnosis. It also allows the patient to be placed in one of three well defined stages.


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

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 intestinao and lambda lanes. Most patients fail and develop disease progression.

Alpha heavy chain disease: It is largely common in the Mediterranean region and relatively rare in South-East Asia. No light chain restriction was seen on IHC. A year-old male itestinal presented with complaints of weight loss, small bowel type diarrhoea, features of malabsorption, and pedal oedema. Molecular genetic analysis has shown clonal rearrangement of heavy and light chains, even in early cases responsive to antibiotic therapy.

This correlates with an abnormally short alpha-chain messenger RNA produced in these patients. Behaviour of mixed variety NHIL is dependent upon the extent of more aggressive diffuse component Biopsy of several mesenteric, para-aortic lymph nodes, particularly if they appear abnonnal. IPSID is a variant ijmunoproliferative the B-cell lymphoma of mucosa-associated lymphoid tissue MALTwhich involves mainly the proximal small intestine resulting in malabsorption, diarrhea, and abdominal pain.

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 Abnormalities involve the immunoprpliferative small intestine, the entire small intestine, or rarely just the ileum or the small intestine in combination with either stomach or colon. Smwll cells are CD20 negative and CD positive.

Immunoproliferative small intestinal disease IPSID was recently added to the growing list of infectious pathogen-associated human lymphomas. Our expenence with stage C disease confirms these observations Am J Surg Pathol.

Cytogenetic studies demonstrated clonal rearrangements involving predominantly the heavy and light chain genes, including t 9;14 translocation involving the PAX5 gene.

No kappa or lambda light chain restriction was present. A 10cm long resection ofthe firstjejunal loop with adjacent mesentery and mesentenc lymph nodes. The infiltrated pattern is most sensitive and specific finding followed by a nodular pattern. Funding is constantly needed for new projects and to update and refurbish existing facilities.
