1
leukemia vs. lymphoma
leukemia - bone marrow involvement
-cells in peripheral blood
lymphoma - lymph node
2
leukemoid rxn
inflammatory response to infection
WBC elevated with neutro and band cells - left shift
increased leukocyte alk phos
3
leukemoid rxn vs. CML
WBC elevated with band cells - left shift - in both
CML - no LAP
LR - elevated LAP - leukocyte alk phos
4
hodgkin lymphoma
local group nodes
prognosis - stage - better than NHL
reed sternberg cells
bimodal distribution
EBV association
5
non-hodgkin lymphoma
multiple peripheral nodes
extranodal involvement
majority B cells
incidence peak 20-40yo
HIV and autoimmune association
6
reed stern berg cells
owl eyes
hodgkin lymphoma
CD15 and CD30 positive
better prognosis - stromal or lymph rxn to RS cells
-lympho rich - best prognosis
