A

By 5 fold

21

Cytokines that increase in Hodgkin lymphoma

A

IL1-9
TGF-beta
TNF

24
Q

Clinical features of Hodgkin lymphoma

A

Peripheral lymphadenopathy
Spread through lymph
B symptoms - night sweats, fever, weight loss
Alcohol induced pain in affected lymoh node
Cough , chest pain, dysnoea ( young patients)

25
Q

2 types of Hodgkin lymphoma based on immunochemistry and morphology

A

Classical HL - 90%

Nodular lymphocyte predominant Hodgkin lymphoma

26
Q

Histo logical classsifiation of Hodgkin lymphoma

A

Lymphocyte rich - 5%
Nodular sclerosing- 70%
Mixed cellularity - 20-25%
Lymphocyte depleted- less than 2%

27
Q

What is lymphocyte rich Hodgkin lymphoma

A

Infiltrate with small lymphocyte , few eosinophils, R-S cells , mononuclear cells

28
Q

What is nodular sclerosing Hodgkin lymphoma

A

Broad bands of connective tissue divide lymph node into nodules
Mixture of R-S, mononuclear H cells, plasma cells, macrophages, eosinophils

29
Q

What is mixed cellularity Hodgkin lymphoma

A

Infiltrate of same cells like other types with a lot of R-S cells
Focal necrosis
Fibrosis

30
Q

Lymphocyte depleted Hodgkin lymphoma

A

High mononuclearr hogdkin cells
R-S present
Few lymphocytes

31
Q

In which stage of Hodgkin lymphoma do you mostly see lymphocyte depleted Hodgkin lymphoma

A

III or IV

32
Q

Is lymphocyte depleted Hodgkin lymphoma common in HIV + patients

A

Yes

33
Q

Staging of Hodgkin lymphoma

A
34
Q

Diagnosis of Hodgkin lymphoma

A
History 
Physical exam 
Lymph node biopsy 
FBC comment
Bone marrow staging 
LDH
Uris acid 
Spleen size imaging to see involvement 
Cx ray - intrathoracic involvement 
CT chest , abdomen , pelvis - extranodal pulmonary involvement
