 AB    Despite a common origin from mature lymphoid cells, non-Hodgkin
       lymphomas (NHL) represent a surprisingly heterogeneous group of lymphoid
       malignancies whose classification is continuously being remodeled. The
       most recent proposal, the Revised European-American classification,
       introduces pathogenetic features among the classification criteria. In
       this respect, knowledge of the molecular pathogenesis of NHL, which is
       based upon genetic lesions leading to activation of proto-oncogenes
       (e.g. BCL-1, BCL-2, BCL-6, c-MYC) or disruption of tumor suppressor
       genes (e.g. p53), is becoming increasingly relevant for the clinician.
       These lesions combine into multiple molecular pathways which are
       selectively associated with distinct NHL types. Thus, for example,
       rearrangements of BCL-1, BCL-2, BCL-6, and c-MYC ar the genetic
       hallmarks of mantle cell, follicular, diffuse large cell, and Burkitt's
       lymphoma, respectively. Overall, from clinical perspective, NHL genetic
       lesions serve three purposes: a) they assist and complement histologic
       diagnosis; b) they provide a molecular marker with prognostic relevance;
       c) they allow evaluation of minimal residual disease through highly
       specific and highly sensitive technologies.
