HL Flashcards
ped vs AYA lymphoma
child: HL, EBV, larger families, mixed cellularity
AYA: NHL, not EBV, smaller families, nodular sclerosing
HL age distribution
AYA, 6-8th decades
HL RF
F
FHx
childhood: large families, low SES, EBV
Classic HL subtypes
Nodular sclerosis (70%): localized, better px
Mixed cellularity (20%): developing countries, EBV
Lymphocyte rich (5%): better px
lymphocyte deplete (1-2%): worse px, EBV
HL biopsy type and reason
excisional
RS cells are few, in inflammatory background
CD30 L+L
HL
PMNHL
ALCL (CD15 neg)
minority of DLBCL
RS cell altered pathway
NFkB
JAK/STAT
cHL vs NLPHL IHC
cHL: CD30 and 15 ; CD45 neg
NLPHL: CD45 ; neg CD 15 and 30
HL presentation
80% lymphadenopathy: painless, rubbery, firm
2/3 mediastinal mass
1/3 B symptoms

II: 2+ nodal regions on same side of diagphragm or localized extralymphatic and 1+ LN
III: both sides of diaphragm
IV: diffuse/disseminated; liver, lung, BM
A: absence of B symptoms
B: B symptoms
E: extranodal
