Leukemias Flashcards
Low RBCs –> Anemia
Low WBCs –> Infection
Low Platelets –> Hemorrhage
Leukemia
Associated with Down Syndrome
Peripheral blood and bone marrow have increased lymphoblasts
ALL
(T-cell)
Acute Lymphoblastic Leukemia/Lymphoma
AML both are associated with Down, but
only ALL has lymphoblast in BM, not just peripheral
TdT+ (Pre- T/B cell marker)
CD10+ (Pre-B cell marker)
ALL
(T-cell)
Acute Lymphoblastic Leukemia/Lymphoma
CD10+ = positive prognosis
Children
Responsive to therapy
Mediastinal mass (+/-) SVC syndrome
ALL
(T-cell)
Acute Lymphoblastic Leukemia/Lymphoma
May go to CNS or testes
ALL
(T-cell)
Acute Lymphoblastic Leukemia/Lymphoma
Smudge cells
Increased BCL2 expression
CLL –> CieLL
(B-cell)
Chronic Lymphoblastic Leukemia/
small lymphocytic lymphoma
BabyCieL (BCL) is my little smudge
(CLL the Cooky eLderLy)
auto-imm. Hemolytic Anemia
Painless Lymphadenopathy
Splenomegaly
OLD person (>60)
CLL
(B-cell)
Chronic Lymphoblastic Leukemia/
small lymphocytic lymphoma
Splenomegaly
Dry Tap
Lymphadenopathy (+/-) !!!!!!
Hairy cell leukemia
B-cell
Male
BRAF mutation
Hairy cell leukemia
Auer Rods
Myeloperoxidase + cytoplasmic inclusions
Old men
AML
Acute Myelogenous Leukemia
&
APL
Acute Promyelocytic Leukemia
(MPO+ cytoplasmic inclusions more common in APL)
Risk factors include: Down Syndrome alkylating chemotherapy radiation myeloproliferative disorders
AML
Acute Myelogenous Leukemia
t(15,17 ) is an AML Subset
Acute Promyelocytic Leukemia (APL)
t(9,22)

(myeloid stem cell proliferation)
Chronic myelogenous Leukemia
Responds to BCR-ABL tyrosine Kinase inhibitor
Imatinib
CML
(myeloid stem cell proliferation)
Chronic myelogenous Leukemia
(C My Littile tinib)
Dysregulated production of Myeloblast (neutrophils, myelocytes, basophils)
SPLENOMEGALY
May transfrom to ___

CML
(myeloid stem cell proliferation)
Chronic myelogenous Leukemia
(C My Little Lap cat)
