title: [Cytogenetic and molecular aspects in MALT lymphomas].
abstract: Cytogenetic and molecular results in 10 patients with extranodal lymphoma (MALT): 5 low grade and 5 high grade, were compared with the results observed in nodal lymphomas. This study suggests that there are cytogenetic differences between extranodal and nodal low grade lymphomas. Both molecular analysis by conventional Southern blot with probes for the major and minor regions of bcl-2 gene, and PCR analysis with primers from these regions, showed that t (14; 18) is a sporadic event in MALT lymphomas.
