ABSTRACT
Multiple lymphomatous polyposis (MLP) is an uncommon type of primary non-Hodgkin's gastrointestinal B cell-lymphoma characterized by the presence of multiple lymphomatous polyps along the gastrointestinal tract. Unlike MALT-lymphoma, MLP has a strong tendency for histologically monomorphic character, extra-digestive localization, rare lymphoepithelial lesion and poor prognosis. The malignant cells of MLP share morphological, immunohistologic and cytogenetic similarities with cells of node-based mantle cell lymphoma. We report a case of mantle cell lymphoma presenting with MLP involving various segments of the gastrointestinal tract, skeletal muscles of the right thigh and bone marrow observed in a 71-year-old woman who complained of lower abdominal pain and a palpable right thigh mass.

Multiple lymphomatous polyposis (MLP) is a distinctive type of primary gastrointestinal lymphoma, characterized by multiple polyps involving long segments of the gastrointestinal tract. Because MLP has a high tendency toward extraintestinal involvement such as bone marrow, lymph node, spleen and liver, MLP can cause various clinical manifestations and has a poor prognosis. We report a case of gastrointestinal MLP, who had an unusual conjunctival involvement during the course of anti-cancer chemotherapy.

Multiple lymphomatous polyposis(MLP) is an interesting clinical entity of non-Hodgkin's lymphoma(NHL) and is defined as B-cell lymphoma characterized by the presence of multiple lymphomatous polyps along the gastrointestinal tract. Recently MLP has been considered as a variant form of mantle cell lymphoma(MCL). The median survival of patients with MCL is only 3 years, and none of the available conventional chemotherapy regimens appears curative. Encouraging results have been reported with high dose chemotherapy with autoSCT and alloSCT for its treatment. We introduce 4 cases of MLP diagnosed as MCL by morphologic and immunologic method. The common clinical findings of these cases were splenomegaly (4/4), multiple intraabdominal lymphadenopathy (4/4), and advanced stage (3/4) at presentation. The overall remission duration was relatively short (5-27 months) and three of four cases relapsed after conventional chemotherapy or autologous stem cell transplant. Our report suggests that MCL presented as MLP is a high risk subgroup of NHL and more aggressive approach may be needed for cure.

Multiple lymphomatous polyposis (MLP) is a term used to describe malignant lymphoma of the gastrointestinal tract that manifest as polyposis. MLP is believed to represent gastrointestinal involvement by mantle cell lymphoma (MCL), primarily based on its histologic and immunophenotypic similarities with MCL. We have experienced a case of MCL presented as a peculiar feature of multiple lymphomatous polyposis in a 49-year old male patient. He had been diagnosed diffuse large B cell lymphoma of nasopharynx and treated by radiation therapy and CHOP chemotherapy. He newly developed MCL after 10 years in complete remission of diffuse large B cell lymphoma. After newly developed lymphoma was compared with former diagnosed lymphoma, we concluded that they were not same type each other. We reviewed a total of 13 patients including this case, of MLP, which were reported in various Korean literature, and literatures are reviewed.

We describe two cases of multiple lymphomatous polyposis in the gastrointestinal tract from the esophagus to the rectum. Clinical findings, histopathologic and immunohistochemical findings in paraffin embedded tissue are discussed. It is important to recognize this rare form of gastrointestinal lymphoma because of the prognostic and therapeutic implications.
