Leukocytosis
Reduction in number of WBC less than 4400/uL
Leukopenia
Normal differential WBC consists of - Neutrophils
50% to 60%
Malignancies that arise from hematopoietic stem cells
Leukemia
Malignant transformation of one stem cell which proliferates in bone marrow and overflows into peripheral blood of affected pt
Leukemia
Major deficiency of erythrocytes, platelets and leukocytes
Leukemia
Less aggressive form of leukemia
Chronic Leukemia
Malignancy of myeloid immature WBC

Chronic myelogenous leukemia progress into
Blast phase , more severe
Deficiency of normal cells and invasion of cancerous cells into tissue
Leukemia
Diffuse, non tender swelling that may or may not be ulcerated which results in diffuse gingival enlargement
Leukemia
Leukocytosis 30,000-100,000 per mm3 with mainly immature form
Acute leukemia
