Abstract
As a wide range of disorders underlie haemophagocytic syndrome, a rapid distinction between benign polyclonal and malignant monoclonal lymphoid proliferations is critical. We investigated whether polymerase chain reaction (PCR) amplification of immunoglobulin heavy chain gene rearrangement could efficiently detect clonal B-cell populations in non-diagnostic marrow for B-cell lymphoma-associated haemophagocytic syndrome (B-LAHS). On amplifying two DNA samples per biopsy, no reproducible monoclonal PCR result was found in reactive haemophagocytic marrows. In contrast, four out of nine assessable B-LAHS patients with histomorphologically and immunohistochemically lymphoma-free bone marrow showed a reproducible monoclonal immunoglobulin heavy chain gene rearrangement. At the molecular level, two B-LAHS patients had lymphoma-free marrow as demonstrated by patient-specific PCR, suggesting that haemophagocytic marrow is not always associated with lymphoma involvement. PCR-based demonstration of clonal B-cell populations in marrow would add an extra dimension to B-LAHS diagnosis.
