Although no recurrent chromosomal alterations have been identified in FDCS, the tumors often show complex karyotypes with loss of whole or partial chromosomes being the most frequent aberration. Losses frequently occur in regions harboring important tumor suppressor genes.<ref name=":2" />

FDCS primarily shows alterations in the NF-κB signaling pathway. Unlike the dendritic cell and histiocytic neoplasms of hematopoietic origin, aberrations in the MAPK pathway are uncommon.
