Infectious mononucleosis in a patient with Hodgkin's disease.

The case is presented of a patient, treated for Hodgkin's disease, who contracted infectious mononucleosis more than 3 years later. While Epstein-Barr virus has been considered a possible etiologic factor in Hodgkin's disease, the sequence of events reported in this case has to be interpreted as evidence against a causal relationship between the virus and Hodgkin's disease in this patient.
