Richter syndrome is a rare condition in which chronic lymphocytic leukemia (CLL) changes into a fast-growing type of lymphoma. Symptoms of Richter syndrome can include fever, loss of weight and muscle mass, abdominal pain, and enlargement of the lymph nodes, liver, and spleen. Laboratory results may show anemia and low platelet counts (which can lead to easy bleeding and bruising).
