Left supraclavicular lymphadenopathy
Abdominalmalignancy especially gastric cancer
Right supraclavicular lymphadenopathy
-chest cavity malignancy especially lung cancer
Mediastinaltymphadenopathy
Lymphoma
Reed sternbergcells
Hodgkin lymphoma
Owl eye
Auer rods
AML
Apml genetics
Translocation15,17
Apml tx
All-trans retinoicacid
Note that traditional chemo will cause di c due to release of coagulants in granuleswhen cells die
AML genemutation with worst px
11q23
AML m 0
Minimal different-tas
All blasts
No aver rods or granules
AML M1
Some differentiation
All blasts
Aver rods andgranuls
AML m2
More differentiation
Still at least 20% blasts since it’s Am l but more mature cells as well
AML m3
A P M L
AML my
Myelomonocytic
NS E orwright-giesma stain
AML m5
Monoblastic/ monocytic “
Oftenextramedullary eg C N S because of the monocytes
AML m6
Pure erythroid
Also myeloblasts…
AMC m7
Megakaryoblastie
Need flow not just microscopy
Therapies that may cause AML
Chemo-alkylating andtopossomerase 2 inhibitors
Alkylating agents e.g.
Busulfan
Cydophosph amide
Is of amide
Topoisomeraseinhibstorse eg.
E topside
Doxorubicin
TopoisomeraseinhibitorAML
Faster thanaltylatingagents
1-3 year latency
No MDs phase
Chromosome 11 and mll gene
Alkylatingagent AML
5-7 year latency often preceded by MDs,
Chromosomes 5 and 7
MDs
Myelodysplasticsyndrome ‘
Pancytopenia due to take over of dys plasticmydlaid cells in bm
Often evolves toaml
Aggressive tx of MDs
’ Stem cell transplant
Generallyreserved forjounger pts with high risk of conversion
Prussian blue
Stains iron
Ring syderoblasts
R BC dysplasia seen in MDs Amons others
Tdt
Terminal deoxynucteo tidy transferase
All and generallylymphoblast marker

Better prognosis
Bone marrow first
Most commonchildhood leukemia
