It is categorized as a lymphoproliferative disorder due to the excessive production of lymphocytes, in<unk>  there is excess production of B-prolymphocytes by the bone marrow. These immature lymphocytes are not normally found in the blood; part of their maturation process is being programmed to produce antibodies against foreign material prior to their departure from the bone marrow. In<unk> , malignant B-prolymphocytes disrupt the adaptive capabilities of the immune system due to the lack of mature B-lymphocytes. It has been suggested that some cases may represent a variant of mantle cell lymphoma.
