Plasma cell leukemia 2017. Primary plasma cell leukemia ppcl is the most aggressive form of the plasma cell dyscrasias. A disease involving the malignant degeneration of a subtype of white blood cells called plasma cells it is the terminal stage and most aggressive form of these dyscrasias constituting 2 to 4 of all cases of plasma cell malignancies. Similar to other forms of mm it is characterized by the expansion of malignant plasma cells within the bone marrow activity capable of resulting in end organ damage such as lytic bone. Plasma cell leukemia pcl represents the most aggressive form of multiple myeloma mm in the spectrum of clinical aggressive ness of plasma cell disorders.
Plasma cell leukemia is an uncommon variant of leukemia that may occur de novo or in association with multiple myeloma. Multiple myeloma patients with low proportion of circulating plasma cells had similar survival with primary plasma cell leukemia patients. Paul kleutghen i am a patient diagnosed in 2014 with primary plasma cell leukemia ppcl a rare and aggressive variant of multiple myeloma and have been very fortunate to find treatment at the division of cellular therapy at the duke university cancer institute. Plasma cell leukemia pcl is a rare and aggressive form of multiple myeloma that involves high levels of plasma cells circulating in the peripheral blood.
Plasma cell leukemia pcl is an aggressive form of multiple myeloma characterized by high levels of abnormal plasma cells circulating in the peripheral circulating blood. Plasma cell leukemia pcl is a plasma cell dyscrasia i e. 1 2 secondary pcl spcl however is a leukemic transformation of end stage mm. It is defined by the presence of 2 10 9 l peripheral blood plasma cells or plasmacytosis accounting for 20 of the differential white cell count and does not arise from preexisting multiple myeloma mm.
Normal plasma cells in the bone marrow produce antibodies that fight infection. It is considered the most aggressive plasma cell disorder and is characterized by a proliferation of malignant plasma cells in the blood and bone marrow plasma cell leukemia cutis is a rare clinical phenomenon with a poor prognosis. It has been commonly associated with the presence of a chromosome translocation involving the immunoglobulin heavy chain igh locus on 14q32 that is t 11 14.
