Cancer Category/Type
HAEM4:Histiocytic and Dendritic Cell Neoplasms (WHO 4th ed.)[1]
Stroma-derived neoplasms of lymphoid tissues (WHO 5th ed.)[2]
Cancer Sub-Classification / Subtype
Mesenchymal dendritic cell neoplasms (WHO 5th ed.)[2]
Definition / Description of Disease
Follicular dendritic cell sarcoma (FDCS) is a neoplasm with morphologic and immunophenotypic features of follicular dendritic cells, which are normally present in lymphoid follicles and are derived from mesenchymal cells of lymphoid tissues.
Synonyms / Terminology
Follicular dendritic cell tumor
Dendritic reticulum cell tumor (no longer used)
Epidemiology / Prevalence
Put your text here
Clinical Features
Put your text here
Sites of Involvement
- Extranodal sites (79%)
- Liver, spleen, and GI tract most common
- Any site may be involved
- Lymph nodes (~15%)[3]
Morphologic Features
Put your text here
Immunophenotype[1][3]
| Finding | Marker |
|---|---|
| Positive (lineage-defining) | One or more of CD21, CD23, CD35 |
| Positive (frequent) | CXCL13, clusterin, podoplanin, fascin, vimentin |
| Positive (variable) | CD68, EMA, S100 |
| Negative (universal) | CD1a, langerin, CD34, CD45, lysozyme, CD163, MPO, CD3, CD79a, cytokeratins, HMB-45 |
Chromosomal Rearrangements (Gene Fusions)
The following rearrangements have been reported in individual cases, but whether they are recurrent is not yet known.
| Chromosomal Rearrangement | Genes in Fusion (5’ or 3’ Segments) | Pathogenic Derivative | Prevalence |
|---|---|---|---|
| EXAMPLE t(9;22)(q34;q11.2) | EXAMPLE 3'ABL1 / 5'BCR | EXAMPLE der(22) | EXAMPLE 5% |
| EXAMPLE t(8;21)(q22;q22) | EXAMPLE 5'RUNX1 / 3'RUNXT1 | EXAMPLE der(8) | EXAMPLE 5% |
Characteristic Chromosomal Aberrations / Patterns
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.[3]
Genomic Gain/Loss/LOH

| Chromosome Number | Gain/Loss/Amp/LOH | Region |
|---|---|---|
| EXAMPLE 8 | EXAMPLE Gain | EXAMPLE chr8:0-1000000 |

Gene Mutations (SNV/INDEL)
Put your text here and/or fill in the tables
| Gene | Mutation | Oncogene/Tumor Suppressor/Other | Presumed Mechanism (LOF/GOF/Other; Driver/Passenger) | Prevalence (COSMIC/TCGA/Other) |

Genes and Main Pathways Involved
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.
Diagnostic Testing Methods
The only current method of diagnosis is tissue biopsy with immunohistochemistry. FDCS must be differentiated from other mesenchymal dendritic cell neoplasms, histiocytic and dendritic cell neoplasms, and non-hematopoietic tumors such as carcinoma, sarcoma, or melanoma which may show histologic similarities.
