Molecular Genetics of Rare Lymphomas

Non-Hodgkin’s lymphoma represents a heterogeneous group of malignancies with diverse clinical manifestations, histologic characteristics, and biologic behavior. Recent improvements in pathologic diagnosis as well as the application of novel molecular biological techniques in clinical routine have led to the distinction of various subtypes of malignant lymphoma that occur at rather low frequencies. These lymphoma subtypes are here referred to as “rare lymphomas”.
