Recurrent chromosomal abnormalities in lymphomas in fine needle aspirates of lymph node.

The detection of specific chromosomal abnormalities is important in the diagnostic workup of aggressive lymphomas, giving its impact on the treatment strategies and prognosis. This has been accomplished by using the fluorescent in situ hybridisation method (FISH) performed on fine needle aspiration (FNA) specimens what is attractive in the diagnosis of lymphoma in the comparation with other methods for collecting samples. The cytogenetic analyses were performed in series of 80 patients with lymphoma (43 women and 37 men, median age 48, range 3-90 years).
