title: Epstein-Barr virus-associated lymphoproliferative disorder presenting as apparently isolated gastrointestinal lesions in childhood.
abstract: We present an unusual case of post-transplant lymphoproliferative disorder (PTLD) presenting as apparently isolated gastrointestinal lesions in a pediatric renal transplant recipient. The multiple bowel lesions were related to Epstein-Barr virus and demonstrated the appearance of a monomorphic PTLD that was morphologically indistinguishable from diffuse large B-cell lymphoma. The patient responded to therapy with targeted anti-CD20 immunotherapy. PTLD may manifest as apparently isolated gastrointestinal tract lesions in childhood.
