There have been conflicting reports about the occurrence of the t(14;18)
chromosomal translocation in Hodgkin's disease. A polymerase chain reaction
analysis of biopsy specimens from 21 patients with Hodgkin's disease (HD)
has shown the presence of the t(14;18) translocation in four cases (20%).
All four patients had nodular sclerosing HD. Direct sequencing of the
amplified 14q+ junctions established that the BCL-2 (major breakpoint
region) sequence was fused to an Ig joining region (JH) (J6 in all four
cases). Different breakpoints were observed in each case but were similar
in nature to the breakpoints described in follicular lymphoma. The exact
nature and cell of origin in HD remains obscure, although the presence of
the t(14;18) translocation may reflect either a B-cell origin in these
cases or associated lymphoid hyperplasia.
