Abstract

Nine patients with chronic lymphocytic leukemia (CLL) who also developed diffuse histiocytic lymphoma (DH) are described. The incidence of patients with CLL developing DH was at least 3.3%. CLL existed for a median of 2 years before the diagnosis of DH. DH presented in 8 patients with abdominal symptoms and/or enlarging lymph nodes, spleen and liver. There were no consistent laboratory abnormalities associated with the onset of DH. In 4 of the patients the DH appeared to be localized. Eight of the 9 patients have died with a median survival of 2 months from the diagnosis of DH. Whether DH occurs as a result of "blastic transformation" of pre-existing CLL or is a second, unrelated malignancy is not certain. It is hypothesized that utilizing current therapies for DH might favorably influence survival.
