What is known about the cause of Hodgkin Lymphoma?
Cause is unknown
How does Hodgkin Lymphoma typically spread?
Starts in a single location and then spreads
Where does Hodgkin Lymphoma originate?
Either above or below the diaphragm
How does Hodgkin Lymphoma behave when it starts above the diaphragm?
Stays confined to lymph nodes for a while (ex: axillary nodes)
How does Hodgkin Lymphoma behave when it starts below the diaphragm?
Spreads rapidly to extralymphoid sites such as the liver
What cells are characteristic of Hodgkin Lymphoma?
Reed–Sternberg cells (giant, multinucleated; very specific to Hodgkin)
What are Hodgkin cells?
Mononucleated cells that proliferate in lymph nodes
