Abstract

Mantle cell lymphoma (MCL) of the gastrointestinal tract is a rare form of primary gastrointestinal lymphoma. MCL of the gastrointestinal tract can involve the stomach, small intestine or colon. The major subtype of MCL is characterized by the presence of multiple lymphomatous polyps along the gastrointestinal tract. So multiple lymphomatous polyposis (MLP) has been considered as a variant form of MCL. The diagnosis of high-grade variants of MCL is a particular challenge, as these tumors exhibit a broad spectrum of morphologic findings that can be misinterpreted as other type of NHL. The development of immunohistochemical and molecular assays for MCL has allowed more accurate diagnosis of cases. We report a case of MCL with feature of colits involving duodenum, colon and rectum observed in a 60-year-old man who complained of low abdominal discomfort.
