CLL Flashcards
(257 cards)
B. CHRONIC LYMPHOPROLIFERATIVE DISORDERS
● Proliferation of lymphocytes which are abnormal because they are unresponsive to antigenic stimuli.
Chronic Lymphocytic Leukemia (CLL)
● Less likely to undergo blastic transformation
Chronic Lymphocytic Leukemia (CLL)
● Predisposition to autoimmune hemolytic anemia (AIHA)
Chronic Lymphocytic Leukemia (CLL)
● is predominant in males (3:1 ratio)
Chronic Lymphocytic Leukemia (CLL)
● CLL Cytogenetic abnormality:
➢ Extra Ch12
➢ t(14q) Translocation on the long arm of Ch14
B cell: produces antibodies due to presence of antigen (normally increases in synchrony)
Chronic Lymphocytic Leukemia (CLL)
Chronic, and involves mature cells
Chronic Lymphocytic Leukemia (CLL)
Types of AIHA:
Warm AIHA (IgA and IgG) and Cold AIHA(IgM)
Duplicated Ch 12
Extra Ch12
marker for Lymphocytic Leukemia (all Lymphocytic Leukemia have this)
Extra Ch12
predicts progression of disease
Extra Ch12
common cell that is involved is the B-lymphocyte
B-CLL
B-lymphocyte is unresponsive to antigenic stimuli = do not function well (abnormal)
B-CLL
Dormant B-cells
B-CLL
o Due to proliferation (useless), they accumulate but stay dormant in the peripheral blood, bone marrow or in the lymph nodes
Dormant B-cells
o Cannot produce Ab even with the presence of Ag
Dormant B-cells
B-CLL or T-CLL
Rare
T-CLL
disseminated in the circulation/does not accumulate
T-CLL
Key features: appearance of rash (skin and CNS is involved)
T-CLL
Enlarged lymph nodes, spleen and liver
Chronic Lymphocytic Leukemia (CLL)
Pruritus
Chronic Lymphocytic Leukemia (CLL)
: due to skin infection due to Herpes zoster
Pruritus
Affects more of males; 50-60 years old
Chronic Lymphocytic Leukemia (CLL)
