A 65-year-old man who had an 8-year history of chronic lymphocytic leukemia was admitted to our hospital on February 19, 1998 because of high fever, dry cough, and weight loss. Laboratory data on admission included serum lactate dehydrogenase at 980 IU/l, CRP at 21.8 mg/dl, and soluble interleukin-2 receptor at 7,280 U/ml. The results of serological tests for Epstein-Barr virus (EBV) antibodies were as follows: EBV capsid antigen IgG 1:2560, EBV early antigen IgG 1:640, and EBV nuclear antigens 1:20. Computed tomography revealed diffuse interstitial pneumonia in both lungs, hepatosplenomegaly with multiple nodules, and enlarged intra-abdominal lymph nodes. In addition, Gallium-67 scintigraphy demonstrated abnormal accumulations. Although the patient initially responded well to combination chemotherapy, he eventually deteriorated and died on November 2, 1988, despite salvage chemotherapy. Postmortem needle biopsy specimens from the liver and spleen revealed diffuse proliferation of polymorphic large lymphoma cells. The lymphoma cells were positive for L-26, latent membrane protein 1, and EBV nuclear antigen, but negative for UCHL-1 and CD3, 5, 10, and 30. In situ hybridization procedures disclosed the presence of EBV-encoded small RNA in lymphoma cells. These findings suggested the possibility of association with EBV infection in some cases of Richter's syndrome.

Richter's syndrome (RS) is the development of an aggressive lymphoma in patients with chronic lymphocytic leukaemia (CLL). In humans, RS occurs in 2-20% of CLL, which transform into diffuse large B-cell lymphoma but reports in dogs are scarce. This study retrospectively describes eight dogs with CLL progressing into RS. A database including 153 dogs with CLL (93T CD8+ and 55 B-CLL) was interrogated and RS was demonstrated in eight cases (representing 5.2% of total CLL): two with T-cell (2.2% of T CLL) and six with a B-cell immunophenotype (10.9% of B-CLL). When RS occurred, lymphocytes were decreased compared to CLL. Five dogs had anaemia and two dogs thrombocytopenia. Frequent clinical signs included lymph node swelling, coughing, vomiting, neurological signs and weight loss. Independently from the therapy, RS was associated with a short survival (median 41 days). RS should be considered as an unfavourable evolution in canine CLL.
