Richter syndrome: an aggressive transformation.

A 71-year-old male patient named M.R. was diagnosed with chronic lymphocytic leukemia (CLL). At the time of diagnosis, M.R. had generalized lymphadenopathy and splenomegaly, which caused him to experience significant abdominal discomfort. M.R. was treated with six cycles of fludarabine, cyclophosphamide, and rituximab (FCR), which is standard first-line chemotherapy, and tolerated this fairly well. His lymphadenopathy quickly resolved and, aside from mild nausea, had no complications from treatment.
