title: Composite lymphoma: report of a unique case.
abstract: Composite lymphoma with more than one well demarcated non-Hodgkin's or Hodgkin's lymphoma in the same organ or mass is rare. Only 22 such cases, each with two lymphomas, have been reported. We describe a unique case in which there were three non-Hodgkin's lymphomas, according to the Rappaport's nomenclature, in the spleen and abdominal lymph nodes.
