Acute is rapidly fatal due to the buildup of undifferentiated blast cells and associated marrow failure

Where as marrow continues to function in chronic leukaemias

Question 6

Answer 6

Anaemia

Thrombocytopenic bleeding i.e. purpura/petechiae & mucosal bleeding

Neutropenia related bacterial/fungal infections

Question 7

Where in a lymph node are various lymphoid cells found?

Answer 7

B cells found in follicles. Undergoing selection/expansion in germinal centres & naïve cells in the mantle zone

T cells in paracortex

Plasma cells in medulla

Question 8

Lymphadenopathy is very common in Lymphoma, what about it would suggest a lymphoma instead of say an infection?

Answer 8

Localised & Painless (if it’s painful more likely to be a bacterial inf)
