Abstract

Most primary gastrointestinal lymphomas are B-cell origin. T-cell lymphomas of the intestine comprise the small portion of gastrointestinal lymphomas. Peripheral T-cell lymphomas (PTCL) rarely affect the gastrointestinal tracts at their initial presentation and the majority of primary gastrointestinal PTCL involve the small intestine. There has been few reports about the diffuse and extensive involvement of gastrointestinal tracts by PTCL. In Korea, there has been no report of a primary gastrointestinal PTCL so far. The common manifestations of PTCL involving the gastrointestinal tracts are abdominal pain, gastrointestinal bleeding, perforation, and diarrhea. However, these are not sufficient for the correct diagnosis. Several other gastrointestinal diseases may mimic PTCL. Its low incidence and clinical similarity to other gastrointestinal diseases make a correct diagnosis difficult. We report a case of primary gastrointestinal PTCL involving the whole gastrointestinal tracts, which rarely casuses massive bleeding, with a review of literatures.
