Perforated rectal lymphoma in a renal transplant recipient: report of a case

Abstract

Purpose: We report the case of a renal transplant recipient with rectal lymphoma manifested by sudden onset of abdominal pain from a perforated rectum who was treated successfully with prompt surgical resection and reduction of immunosuppressants.

Methods: An emergent anterior resection with Hartmann's procedure was done. Immunosuppressants were drastically reduced by discontinuation of cyclosporine.

Results: Pathologic examination showed diffusely infiltrated large-cell malignant lymphoma with an immunoblastic feature. The patient has been followed-up for four years, with no tumor recurrence or graft rejection.

Conclusion: Rectal lymphoma, although rare, should be kept in the list of differential diagnoses for transplant recipients who exhibit lower gastrointestinal bleeding, intestinal obstruction, or abdominal pain.
