Non-hodgkins Lymphoma Flashcards
Chromosomal translocations for mantle cell lymphoma
t(11;14), cyclin D1 over expression
Chromosomal translocations for Follicular lymphoma
t(14;18), over expression BCL 2
Chromosomal translocations for Burkitt lymphoma
t(2;8),t(8;14), and t(8;22), fuse Ig gee to c-myc
Chromosomal translocations for DLBCL
Germinal center type: over express BCL6 mRNA
Post germinal center type: over express BCL 2 mRNA, poor prognosis
Chromosomal translocations for anaplastic large cell lymphoma
t(2;5), alk gene fusion with nucleophosmin
Chromosomal translocations for marginal zone lymphoma
t(11;18), MALT 1 translocation
Germinal center DLBCL
Cd 10+, Mum 1 negative, BCL 6 +
Better prognosis
Non-germinal center DLBCL
Cd 10-, mum 1 positive, bcl2 positive
Worse prognosis
Peripheral T cell lymphoma
CD 3 and 43 positive
Kappa it lambda negative (rules out B cell)
Cd 20, 30, 34, 56 negative
Aggressive NK cell leukemia/lymphoma
CD 45 and 55 positive Cd 3,4,5,8,20 negative B and T cell gene rearenagements negative Ebv positive Often presents with dic
Large granular lymphocyte leukemia
Rheumatoid arthritis, fever, neutropeniA, splenimegaly
TdT, cd 3,8,56,57 positive
Tx with mtx, cyclophosphamide chlorambucik or steroids
