General term for non-specific prolymphocytic leukemia (unknown if B-cell or T-cell) A type of chronic lymphocytic leukemia (CLL), in which too many immature white blood cells (prolymphocytes) are found in the blood and bone marrow
Patients typically have systemic disease at presentation, with bone marrow and peripheral blood involvement as well as hepatosplenomegaly, generalized lymphadenopathy, and skin infiltrates.
Due to the systemic nature of this disease, leukemic cells can be found in peripheral blood, lymph nodes, bone marrow, spleen, liver and skin. A high lymphocyte count (> 100 x 109/L) along with anemia and thrombocytopenia are common findings. HTLV-1 serologies are negative and serum immunoglobins are within normal limits with no paraproteins present
