Follicular lymphoma (FL) is a B-cell lymphoma that recapitulates the germinal center (GC)-B-cell stage of differentiation and in most cases form neoplastic follicles that resemble the normal GC. Normal GCB-cells do not express the anti-apoptotic protein B-cell leukemia/lymphoma 2 (BCL2) and they readily undergo apoptosis if they do not have a high affinity antigen receptor that will transmit survival signals on recognition of the antigen. The vast majority of FL has a translocation that leads to an inappropriate constitutive expression of the BCL2 protein that protects the cell from apoptosis. This cell can survive for long periods in the GC environment and undergoes further genetic alterations that eventually establish the neoplastic clonal population as a FL. These critical secondary changes are of great interest in understanding the evolution of a pre-neoplastic clone with BCL2 translocation to a malignant lymphoma.
