Extensive primary lymphoma of the gastrointestinal tract

Multiple lymphomatous polyposis of the colon and rectum. Report of a case and review of the literature

BACKGROUND

Multiple lymphomatous polyposis is a non-Hodgkin's centrocytic lymphoma that presents with polyposis of the mucosa and can be found anywhere in the gastrointestinal tract.

METHODS

On the basis of a new case and 31 cases in the literature since 1971, the treatment is discussed.

CONCLUSIONS

Surgery is not indicated and chemotherapy is the appropriate treatment.

Cecocolic intussusception in multiple lymphomatous polyposis of the gastrointestinal tract. Report of a case

A rare case of recurrent cecocolic intussusception in an adult patient with multiple lymphomatous polyposis of the gastrointestinal tract is presented. Clinical features, especially the difficulty in distinguishing this entity from adenomatous polyposis on colonoscopy, and histopathology are discussed. It is important that surgeons and colonoscopists be aware of this rare form of diffuse gastrointestinal lymphoma because of therapeutic implications.

HTLV-I-associated lymphoma involving the entire alimentary tract and presenting with an acquired immune deficiency

A patient with HTLV-I-associated adult T cell lymphoma presented like a patient with the acquired immune deficiency syndrome (AIDS) with peripheral lymphadenopathy, profuse diarrhea, weight loss, night sweats, and multiple opportunistic infections. Infections included cytomegalovirus, Pneumocystis, Histoplasma, Strongyloides, Giardia, and Staphylococcus aureus. Histoplasma has not previously been associated with this lymphoma. The lymphoma involved the entire alimentary tract from pharynx to rectum, which has not previously been reported for adult T cell lymphoma, and is rare for any lymphoma, with only one case reported in this century. Despite extensive gastrointestinal involvement, steatorrhea was not present, perhaps due to preservation of normal intestinal villous architecture.

Diffuse lymphomatous polyposis of the gastrointestinal tract. A case report with immunohistochemical studies

A case of diffuse lymphomatous polyposis of the gastrointestinal tract is reported. The patient presented with abdominal pain and weight loss and x-rays revealed multiple polyps involving the entire gastrointestinal tract. Biopsies confirmed the diagnosis of lymphomatous polyposis. The patient also had involvement of the bone marrow and supraclavicular lymph node. Immunologically this lymphoma was characterized as a monoclonal proliferation of B lymphocytes bearing immunoglobulin M, type kappa. Diffuse lymphomatous polyposis of the gastrointestinal tract appears to be a generalized malignancy of uncommitted B cells of Peyer's patches. The migratory properties of these cells may account for the tendency to dissemination of lymphomatous polyposis. Diffuse lymphomatous polyposis of the gastrointestinal tract is a distinct entity, separate from the diffuse gastrointestinal lymphoma known as Mediterranean-type lymphoma.
