1
Q

Leukemoid rxn

A
Left shift (Increase in band cells)
Alk phos would be increased but not in CML!!!
2
Q

Leukemia

A

Low leukocyte alk phos

3
Q

Hodgkin’s lymphoma characteristics

A
Reed-sternberg cells
Local lymph nodes 
B symptoms
May be associated with EBV
Less reed cells, better outcome
PET scan best for staging

Brentaximab also used for advanced

Early- ABVD- Adriamycin, Bleomycin, Vinblastine and Dacarbazinefor all stages

4
Q

Non hodgkins lymphoma characteristics

A

Widespread lymph nodes
B symptoms not as common
May be associated with HIV
Prognosis varies widely

5
Q

Reed sternberg cell

A
Owl eyes
CD30/CD15 positive
CD45 negatve, only lymphoprolifrative disorder that is negative.
Lymphomas always do an excisional biopsy
Under somatic hypermutation
6
Q

Hodgkin lymphoma types

A

Nodular sclerosis
Mixed cellularity
Lymphocyte depletion
Lymphocyte predominance (CD 20+)

7
Q

Nodular sclerosis

A

Most common in women
Mediastinal, supraclavicular, and lower cervical nodes
Good prognosis (low reed sternberg count)
Can see collagen banding on biopsy

8
Q

Mixed cellularity

A

Intermediate prognosis
Is associated with EBV
Lymphocytes and reed sternberg about equal

9
Q

Lymphocyte predominance

A

Mostly men, lots of lymphocytes, good prognosis

10
Q

Lymphocyte depletion

A

EBV associated

Poor prognosis

11
Q

Hodgkins lymphoma staging

A

1) 1 LN
2) More than one LN, same side as diaphragm
3) More than one LN, both sides of diaphragm
4) Outside of LN system

12
Q

Burkitt lymphoma

A
B- cell
Africa- Jaw
US- abd
(8:14  2:8  8:22) c-myc translocation
Starry sky pattern
13
Q

Diffuse large well differentiated lymphocytic lymphoma

A

Older Patients (Most common non hodgkins)
Lymph/hepatosplenomegaly
Bone marrow almost always involved
5-7 year survival

14
Q

Mantle cell lymphoma

A

t(11;14) IgH to bcl-1
Lymph/hepatospleenomegaly with fever and night sweats
Poor prognosis—3 years
CD5+

15
Q

Follicular lymphoma

A

Slower growing
t(14;18) IgH to bcl2 so less apoptosis
May be associated with immunodificiency states

16
Q

Adult t-cell leukemia/lymphoma

A

Mosly japan, some africa
Lymph/hepatospleenomgaly, skin lesion, and hypercalcemia
Cause: HTLV1

17
Q

Cutaneous T-cell lymphomas

A

Mycosis fungoides- Inflammation, plaque, tumor

Sezary syndrome- Once its in the bloodstream.

18
Q

Multiple myeloma

A

Plasma cell neoplasm
CRAB- Calcium, Renal, Anemia, Bone lysis

Test: serum protein electrophoresis shows a large spike of serum or urine of monoclonal IgG or IgA

Over production of light chain gets stuck in distal renal tubule (kappa bence jones proteins) and causes necroses.
Marrow cells have Russell bodes
X-rays show punched out defects (can produce hyper calcemia because they secrete osteoclast activating factor)
Rouleaux formation shows stacked RBC’s

Staging based on serum albumin levels and B-2 microgloblulin

19
Q

Waldenstrom macroglobulinemia

A

Like multiple myeloma only monoclonal IgM
Get thick blood, clotting
NO BONE LYSIS

20
Q

Monoclonal gammopathy of undetermed significance

A

Also get a M spike electrophoresis without symptoms associated with waldenstrom and multiple myelomas

3 criteria
Monoclonal <10%
No end organ damage

Smoldering the same except with bone marrow plasma cells between 10-60g/dl

21
Q

Acute lymphoblastic leukemia/lymphoma

ALL

A
Less than 15 y/o
Increased bone marrow lymphoblast
TdT and CALLA+
If t(12;21), better prognosis
t(8;14); t(8;22); t(2,8)
t(9;22) Philly!!! Really bad

Children- 60-80% cure
Adults- 30-60% cure

Responds to imitinib, also monitor kidney and use allopurinol

22
Q

Small lymphocytic lymphoma and Chronic lymphocytic leukemia

SLL/CLL

A

Greater than 60 y/o, Men more likely
Often asymptomatic, smudge cell in PBS
Warm Ab autoimmune hemolytic anemia
CLL has more lymphocytosis than SLL

Possible:
Autoimmune hemolytic anemia
Autoimmune Thrombocytopenia
Infections due to Hypogammaglobulinemia

Grading
0- Lymphocytosis
1- with lymphadenopathy (SLL)
2- Organomegaly
3- Anemia
4- Thrombocytopenia

Deletion 11q23 and Alteration 17p is poor prognosis

23
Q

Hairy cell leukemia

A

B cell tumor with hair like projections

Stains TRAP +

24
Q

Acute myelogenous leukemia AML

A
Peaks at 60yo
increased myeloblasts on PBS
