title: Bilateral perinephric diffuse large B-cell lymphoma and synchronous renal oncocytoma.
abstract: An elderly patient who presented with bilateral perinephric diffuse large B-cell lymphoma and concomitant oncocytoma of the same location is reported. To our knowledge, the anatomic proximity of the two tumors at the level of kidneys has not been previously described. Because of the patient's other medical conditions, systemic chemotherapy was not deemed feasible. Subsequently, the proliferation had a favorable response to single-agent monoclonal antibody rituximab.
