Multiple herpes virus co-infection is a very rare complication in patients with chronic lymphocytic leukemia (CLL). We describe a patient with a CLL who developed an herpes virus lymphadenitis. Inmunohistochemical study was positive for HSV-1, HSV-2, and Epstein-Barr Virus (EBV). The coinfection of EBV with a profile of expresion of viral latent genes type III, is usually seen in inmunodepressed patients. To the best of our knowledge, this is the first reported case of a multiple human herpes virus infection mimicking Richter syndrome.
