Q

complications follicular lymphoma

A

slow, so time to develop anti-cancer but more so autoimmune disease e.g. autoimmune hemolytic anemia. (this is a complication in most indolent lymphomas)

23
Q
A

aml or apml; note auer rod

24
Q

histology diffuse large B cell lymphoma

A

lymph node takeover by large, immature B cells (hence “diffuse” “large”)

25
Q
A

diffuse large b cell lymphoma; note dense (“diffuse”) infiltrate of large b cells (far-apart nuclei)

26
Q
A

hodgkin’s lymphoma; note reed-sternberg cell

27
Q

most likely cell to be affected in all

A

b cells

28
Q
A

polycythemia vera

29
Q

causes burkitt’s

A

ebv, almost always in ic patients b/c they are most susceptible to ebv and to immune evasion

30
Q

which cancer/myeloprolif: constant erythropoiesis

A

polycythemia vera

31
Q

what is M protein

A

clonal proteins found in multiple myeloma; usually igg (~50%), can be iga, light chain

m spike is diagnostic

32
Q

markers all

A

CD10+, other B cell markers, some T cell markers

33
Q

histology follicular lymphoma

A

dense, nodular (“follicular”) lymph nodes, tightly packed cells, memory b takeover

34
Q

cells affected: polycythemia vera

A

rbcs; others are unaffected

35
Q

mutation burkitt’s

A

translocation of cmyc to IgH region. igh is constitutively active in B cells so now cmyc survival signal is on.

36
Q

myeloproliferative or cancer? aml

A

cancer. differentiation, maturation, function very much not intact

37
Q
A

multiple myeloma; not always seen but charge on m proteins can make rbcs sticky, called rouleaux formation

38
Q

causes of polycythemia vera

A

primary: bad clone; secondary: hypoxia, high epo, etc

39
Q

cml drug

A

imatinib

40
Q

histology apml

A

even more likely to form auer rods and Azur granules than in general aml

41
Q
A

aml or apml

42
Q

which cancer: philadelphia chromosome

A

CML (and about 30% of adult ALL cases)

43
Q

histology aml

A

auer rods, azur granules, open chromatin

44
Q

fast or slow? burkitt’s

A

super duper fast. fastest of all neoplasms

45
Q

causes aml

A

key one are environmental toxins, e.g. occupational, chemo, radiation, esp. benzene, anything inducing dna breakage

46
Q
A

burkitt’s lymphoma; note “starry sky”

47
Q

sx apml

A

coagulopathy and hemorrhage (DIC)

48
Q
A

multiple myeloma; note “punched out” appearance

49
Q
A

follicular lymphoma; note nodules/follicles

50
Q
A

all

51
Q

mutations apml

A

t(15:17), t(11:17)

52
Q

affected cell follicular lymphoma

A

usually memory b

53
Q

hsct? cml

A

yes if imatinib fails

54
Q

most likely cell to be affected in childhood all

A

committed pre-b cell

55
Q

isolated? diffuse large B cell lymphoma

A

usually isolated, metastatic potential; name “diffuse” comes from lymph node appearance not metastasis
