Blastic plasmacytoid dendritic cell neoplasm (BPDCN)

Definition / Description of Disease

Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a rare, clinically aggressive hematologic malignancy that derives from precursors of plasmacytoid dendritic cells (pDCs)[1][2].

Synonyms / Terminology

  • Agranular CD4+ NK cell leukaemia (obsolete)[1]
  • Blastic NK leukaemia/lymphoma (obsolete)[1]
  • Agranular CD4+ CD56+ hematodermic neoplasm/tumor[1][2]

Epidemiology / Prevalence

  • BPDCN is rare, estimated to represent < 1% of all hematologic malignancies[1].
  • The incidence of BPDCN in the USA: 0.04 cases per 100,000 individuals[3].
  • BPDCN has no known racial or ethnic predilection.
  • Though BPDCN can occur at any age, it more commonly occurs in elderly patients with a mean/median patient age at diagnosis of 61-67 years[1][4].
  • It most often affects males, with a male-to-female ratio of 3.3:1[1].

Clinical Features

Put your text here and fill in the table (Instruction: Can include references in the table)

Signs and Symptoms EXAMPLE Asymptomatic (incidental finding on complete blood counts)

EXAMPLE B-symptoms (weight loss, fever, night sweats)

EXAMPLE Fatigue

EXAMPLE Lymphadenopathy (uncommon)

Laboratory Findings EXAMPLE Cytopenias

EXAMPLE Lymphocytosis (low level)


editv4:Clinical Features
The content below was from the old template. Please incorporate above.

Typical BPDCN patients may have two stages[1]:

o  First stage: affects the skin , usually contained or indolent

o  Second stage:  rapid leukemic spread and multi-organ involvement that eventually leads to death[1].

Sites of Involvement

  • Multiple sites are frequently involved by BPDCN. The three most common are the skin (in 60–100% cases), followed by the bone-marrow and peripheral blood (in 60–90% of cases), and thirdly the lymph nodes (in 40–50% of cases)[1].
  • Upon diagnosis, the central nervous system (CNS) is also frequently found to be involved, and up to one third of patients have CNS involvement at relapse[3].

Morphologic Features

  • BPDCN is commonly characterized by a diffuse, monomorphous infiltrate of small or medium-sized blasts[1].
  • The morphology of the neoplastic cells is similar to lymphoblasts or myeloblasts:  high N: C ratio, eccentrically located nucleus, fine chromatin, a prominent nucleolus and scant amphophilic cytoplasm[1].
  • Mitoses are variable in number, and the Ki-67 rate ranges from 20 to 80%[1].
  • Necrosis may present.

Immunophenotype

Put your text here and fill in the table (Instruction: Can include references in the table)

Finding Marker
Positive (universal) EXAMPLE CD1
Positive (subset) EXAMPLE CD2
Negative (universal) EXAMPLE CD3
Negative (subset) EXAMPLE CD4


editv4:Immunophenotype
The content below was from the old template. Please incorporate above.
  • BPDCN cells express CD4, CD43, CD45RA, CD56, and the pDC associated antigens, including CD123 (IL3 α chain receptor), CD303, TCL1A, CD2AP, and TCF4[1][2][3].
  • BPDCN is characterized by high expression levels of CD123 and weak expression of CD45[1].
  • BPDCN cells are negative for lineage-specific markers including CD3, CD19, and myeloperoxidase[1][3].
  • BPDCN cells also do not express myeloid cell nuclear differentiation antigen (MNDA)[3].
  • BPDCN cells in some cases variably express CD2, CD5, CD7, CD33, CD38, CD68, CD117, HLA-DR, and TdT[1][3].

Chromosomal Rearrangements (Gene Fusions)

Put your text here and fill in the table

Chromosomal Rearrangement Genes in Fusion (5’ or 3’ Segments) Pathogenic Derivative Prevalence Diagnostic Significance (Yes, No or Unknown) Prognostic Significance (Yes, No or Unknown) Therapeutic Significance (Yes, No or Unknown) Notes

The t(9;22) is diagnostic of CML in the appropriate morphology and clinical context (add reference). This fusion is responsive to targeted therapy such as Imatinib (Gleevec) (add reference).


editv4:Chromosomal Rearrangements (Gene Fusions)
The content below was from the old template. Please incorporate above.

A recurrent balanced translocation t(6;8)(p21;q24) involving the MYC locus was exclusively identified in BPDCN[5][6][7][8][9]. The prevalence of MYC translocation in BPDCN is 5% -12%[6]. Rearrangements involving the MYC locus on 8q24 are associated with MYC protein overexpression and specific clinical features, including older onset age and shorter median survival[6]. RUNX2, located on chromosome 6p21, is strongly expressed in pDCs and BPDCN cells. The t(6,8) generates mutant-allele super-enhancer of RUNX2 which may increase the expression of MYC and lead to the development of BPDCN[5]. SUPT3H, a TATA-binding protein-associated factors (TAF)-associated protein, was identified as a novel 8q24/MYC partner in BPDCN[7].

Chromosomal Rearrangement Genes in Fusion (5’ or 3’ Segments) Pathogenic Derivative Prevalence
t(6;8)(p21;q24) 5'RUNX2 super enhancer / 5'MYC increased expression MYC 5-12%[5][6][7][8][9][10]
t(8;var)(q24;var) ? / 5'MYC ?increased expression MYC


editv4:Clinical Significance (Diagnosis, Prognosis and Therapeutic Implications).
Please incorporate this section into the relevant tables found in:
  • Chromosomal Rearrangements (Gene Fusions)
  • Individual Region Genomic Gain/Loss/LOH
  • Characteristic Chromosomal Patterns
  • Gene Mutations (SNV/INDEL)
  • BPDCN is extremely aggressive, with a median survival of 10-19.8 months[1].
  • Age is an adverse impact factor for prognosis[1].
  • Diagnosis is usually established through skin biopsy with immunohistochemistry or flow cytometry[4].
  • Traditional therapeutic approaches include multi-agent chemotherapy, such as CHOP, hyper-CVAD[2][3][4]. However, the traditional chemotherapy is associated with high relapse rate and death[11].
  • A new targeted therapy, Tagraxofusp (SL-401, ELZONRIS) was recently approved.  This agent is a CD123-directed cytotoxin consisting of recombinant human interleukin-3 fused to a truncated diphtheria toxin[2][4][11].
  • For the patients in first complete remission after induction therapy, allogeneic hematopoietic stem cell transplantation (HSCT) is recommended to achieve long-term survival[1][4].

editv4:Characteristic Chromosomal Aberrations / Patterns
The content below was from the old template. Please incorporate above.
  • Chromosomal abnormalities are identified in the majority of BPDCN cases; about two thirds of BPDCN patients have an abnormal karyotype[1].
  • About 75% of BPDCN patients have a complex karyotype, which is defined by three or more abnormalities, including at least one structural abnormality[3].
  • Abnormalities involving the short arm of chromosome 12, the 12p13 locus which contains ETV6 gene, are the one of the most frequent findings in BPDCN (in 64% patients)[1][3].
  • Chromosome 6 (6q23-qter, in 50% patients) and chromosome 13 (13q13-21, in 64% patients) are also frequently involved[1][3].
  • Six major recurrent chromosomal targets were defined in one study[10]. These were 5q, 12p, 13q, 6q, 15q, and 9, which were involved in 72% (5q), 64% (12p and 13q), 50% (6q), 43% (15q), and 28% (monosomy 9) of cases, respectively.

Genetic Diagnostic Testing Methods

  • A dual-color TCF4/CD123 immunohistochemistry stain has been reported to have both high sensitivity and specificity for the diagnosis[16].
  • Immunophenotyping showing expression of pDC antigens and no lineage specific markers is relatively specific for this entity.
  • Chromosome analysis and/or copy number assessment by whole genome microarray or other technology can identify recurrent aberrations.
