Utility of immunophenotypic and immunogenotypic analysis in the study of necrotic lymph nodes
Vega F, Lozano MD, Alcalde J, Pardo-Mindan FJ.
We report a case of complete lymph node necrosis.
No specific aetiology could be determined by morphology, but a B lymphoid population and clonal rearrangement of the immunoglobulin heavy chain gene were demonstrated in immunophenotypic and immunogenotypic studies performed using DNA extracted from paraffin embedded necrotic tissue. In the setting of lymph node necrosis, we suggest that immunohistochemical and gene rearrangement studies may provide additional diagnostic information.
