15
Q

An increase in RBC that is caused by a reduction of fluid in blood, which causes a relative increase in RBC.
Common in people that are vomiting, have diarrhea or are using diuretics

This is secondary to dehydration

16
Q

An increase in RBC that is due to a mutation in JAK2, Causes itching skin and increases the risk of developing a thrombus. Patients have relativly low levels of EPO

A

Polycythemia vera

17
Q

An increase in RBC of EPO either due to medication or hypoxia (increase in altitude)

A

Elevated EPO

18
Q

A reactive leukocytosis, that is common in Adolescence and young adulthood. Condidion makes atypical lymphocytes and splenomegaly.

Associated with Epstein-Barr virus (HHV6)

A

Infectious mononucleosis

19
Q

Reactive leukocytosis that causes Lymphadenitis and Granuloma formation. Caused by Bartonella henselae

A

Cat-scratch fever

20
Q

Most common NHL in children.

Pre-B cells = 4 yr olds
Pre-T cells = 15-20 yr olds

Verry agressive, Pancytopenia, Bone pain, fever, hepatosplenomegaly

A

Acute lymphoblastic leukemia (ALL)

21
Q

Most common NHL of adults, mainly in 60 yr old males. Indolent course, Displaces bone maorrow, involves blood. Is associated with immune abnormalities

A

Chronic lymphocyic Leukemia (CLL)

22
Q

Very common NHL of adults, mainly 60 yr old males. Similar course as CLL except it involves Lymph nodes.

A

Small lymphocytic Leukemia (SLL)

23
Q

leukemia that makes up 40% of NHL. Affects adults age 50 and up. Caused by a mutation in BCL2 gene. May transsition into B cell lymphoma

A

Follicular lymphoma

24
Q

NHL in which abnormal B-cells are found in mantle zones of lymph nodes. Adults males > 50

A

Mantle cell lymphoma

25
Most common lymphoma of adults, Very agressive and rapidly fatal
Diffuse Large B cell lymphoma
26
Fast and agressive leukemia that involves the mandible and maxillae. Common in african children. Causes distortion of the face and bone
Burkitt lymphoma
27
Only NHL covered in this class that affects plasma cells and not B cells. Common in older adults (70). Causes punched out ostrolytic lesions and is associated with a "m-spike' from Bence-Joens proteins
Multiple myeloma
28
leukemia that has Reed-Sternberg cells. Starts at a single node and progresses ina predicable manner. It is painless. 70% of cases are associated with a previous EBV infection
Hodgkin lymphoma
29
A myeloid neoplasm in which Myeloblasts lose their abiliy to differentiate. This neoplam is very agressive, Myeloblasts replace bone marrow and suppress hematopoesis
Acute myeloid Leukemia (AML)
30
Myeloid neoplasm that replaces bone marrow. Myeloid cells can still differentiate but Hematopoesis is disordered. 40% of these neoplasms transform in AML
Myelodysplastic syndromes
31
Myeloid neoplasm; RBC/Granulocyt/Platelet counts are proportions are abnormal. may progress into pancytopenia or splenomegaly
Chronic myeloproliferative disorders
32
Chronic myeloproliferative disorder (Myeloid neoplasm) That causes Extramedullary hemotopesis and makes the pulp of the spleen resemble bone marrow. Philadelphia chromosome
Chronic myelogenous leukemia
33
Chronic myeloproliferative disorder (myeloid neoplasm) That causes Extramedullary hematopoesis, splenomegaly and is often diagnosed in its late stages
primary myelofibrosis
34
Chronic myeloproliferative disorder (myeloid neoplasm) that causes and increase in platelet production and is mostly asymptommatic.
Essential thrombosythemia
35
What are the different types of Chronic myeloproliferative disorders
Chronic myelogenous Leukemia Primary Myelofibrosis Essential thrombocythemia Polycythemia vera
