Term
In Hodgkin's Lymphoma, B symptoms are common. What are the 3 classic B symptoms?
Definition
fever, drenching sweats, and weight loss
Term
What subset of Hodgkin's Lymphoma accounts for 5% of cases?
Definition
Nodular Lymphocyte Predominant Hodgkin's Lymphoma
Term
The majority of cells in Hodgkin's Lymphoma are of what type?
Definition
Non-neoplastic multilineage inflammatory cell background
Term
The nodular lymphocyte type of Hodgkin's affects what age group and gender predominantly?
Definition
Men, 30-50
Term
True or False- Nodular Lymphocyte Hodgkin's is associated with latent EBV?
Definition
False. It is not.
Term
In nodular lymphocyte Hodgkin's, what is special about the morphology of Reed Sternberg cells?
Definition
There is nothing special. Reed Sternberg Cells are hard to find. Instead, we have L& H variants which have  multi-lobed nucleus resembling a popcorn kernel ("popcorn cell")
Term
What is the background that the cells in nodular lymphocyte Hodgkin's are set in?
Definition
A follicular dendritic meshwork that attracts cytokines and chemokines
Term
Nodular lymphocyte Hodkgin's is considered to be non-neoplastic due to the absence of what 2 types of cells?
Definition
PMN's and Eosinophils
Term
What antigens and markers are present in Nodular Lymphocyte Hodkgin's?
Definition
CD45, CD20, OCT2/BOB1 (stain like B cells), lack the classical CD 15 and 30 markers present in CHL
Term
To what is the typical nodular pattern of growth in Nodular Lymphocyte Hodgkin's due to?
Definition
Presence of expanded B-cell follicles, IgH genes undergoing somatic hypermutation (modification that occurs only in germinal center B cells)
Term
What is the prognosis for individuals with Stage I/II nodular lymphocyte Hodgkin's?
Definition
80% of individuals have a median survival of at least 10 years. But, there is frequent relapse potential.
Term
What is the age distribution in Classical Hodgkin's Lymphoma?
Definition
There is bimodal age distribution (15-35)
Term
What disease increases the risk of contracting CHL?
Definition
Infectious mononucleosis
Term
What are the two lymph nodes most commonly involved in CHL?
Definition
Cervical and Mediastinal (75% and 60%, respectively)
Term
What are Reed-Sternberg Cells, and what functions do they serve?
Definition
Reed-Sternberg Cells release factors that induce the accumulation of reactive lymphocytes, macrophages, and granulocytes, which typically make up greater than 90% of the tumor cellularity
Term
What strain of EBV is associated with CHL in developing nations?
Definition
EBV Strain Type 2
Term
What is the standard course of treatment for CHL?
Definition
ABVD therapy
Term
What subtype of CHL is the most common?
Definition
Nodular Sclerosis- 70% of CHL cases
Term
What type of RS cells are present in Nodular Sclerotic CHL?
Definition
Lacunar variant cells
Term
What are the gender and age distribution values for Nodular Sclerotic CHL?
Definition
M:F is equal, and 18-34 is the age distribution
Term
What is the geographic locality of Nodular Sclerotic CHL?
Definition
More common in developed countries
Term
Which subset of CHL has a high incidence of EBV and is more common in developing countries?
Definition
Mixed Cellularity
Term
What is the growth pattern for Mixed Cellular HL?
Definition
There is diffuse efacement by a heterogenous cellular infiltrate, including everything / little nodular sclerosis/ no capsule formation
Term
How common is EBV and B symptoms in Lymphocyte-Rich HL?
Definition
EBV in 30-50% of such cases; due to proliferation of reactive lymphocytes, B symptoms not found
Term
In Lymphocyte Depleted CHL, how are the RS cells unusual?
Definition
The RS cells are infected with EBV in 95% of cases, and there is little cytokine/chemokine production; there is also an abundance of pleomorphic variants of RS cells
Term
What are the common sites of involvement in Lymphocyte Depletion HL?
Definition
Retroperitoneal lymph nodes, abdomen, bone marrow, peripheral nodes uncommon
