It refers to neoplastic proliferation of haemopoietic stem cells characterized by accumulation of mature looking lymphocytes in marrow, lymph node, spleen and marked lymphocytosis.

Clinical feature:
•Age incidence – 45- 75 years
•Average -55 years
•M: F – 2:1
•Common- Generalised lymph node enlargement
•Anaemia
•Fever, sweat, anorexia
•Less common – Splenomegaly, petechi, infection (RTI) , Bone and joint pain.
Laboratory diagnosis
•1) Blood picture
• a) Hb – Mild to moderate reduce.
• b) WBC –Usually 50000 -200000/ cumm. c) ESR – Markedly increased.
PBF
•RBC – Usually normocytic and normochromic.
•Occasional neucleated cells are seen.
•WBC – Shows marked leucocytosis, 90% are mature lymphocytes and monotonous appearance. Smear cells are also seen.
•Platelet – Initially normal but latter markedly reduce.
BONE MARROW
•Cellularity – Hyper celluler.
•Erythropoiesis – Reduce
•Granulopoiesis – Reduce
•Lymphoiesis - Hyperactive. Most cells are mature looking lymphoid cells. Lymphocytes are more than 30% among all nucleated cells.
