Small Intestinal Lymphoma in a Post-Renal Transplant Patient: A Rare Case with Late Presentation

Post-transplant lymphoproliferative disorder (PTLD) is the second most common malignancy in adults who receive solid organ transplants. The overall incidence of PTLD ranges from 1 to 10 % after transplantation and occurs in 1–3 % of patients who are renal transplant recipients [1]. PTLD generally displays B cell lineage derivation, involvement of extranodal sites, aggressive histological characteristics, and clinical behavior [2]. The most common histological type is the diffuse large B cell lymphoma. We here present a rare case of a patient with small intestinal PTLD 16 years after renal transplantation who is completely disease free for 8 years after successful treatment with surgery and combination chemotherapy (CCT).
