lymphomas
hodgkins- less lymph nodes and with reed sternberg cell
t-lymphocyte is defective has 4 subtypes (1:single 2:multiple regions 3:both regions of diaphragm 4:widspread)
nonhodgkins - more lymph nodes caused by HIV
increase in plasma cells in bone marrow; its a circulating blood disorder that is unknown; known to cause defect within the head/skull; what are some S/S for this and treatment

diuretics, bed rest, massage area, elevation
caused by blockage because of parasitic infection
causes swelling (legs, breast, genetalia)
treatment?
elephantiasis
meds regimen to kill the parasite at hand
overgrowth of lymphoid tissue
unicentric vs multicentric define
S/S for this
Castleman disease
