Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is an aggressive and largely incurable hematologic malignancy originating from plasmacytoid dendritic cells (pDCs). Using RNAi screening, we identified the E-box transcription factor TCF4 as a master regulator of the BPDCN oncogenic program. TCF4 served as a faithful diagnostic marker of BPDCN, and its downregulation caused the loss of the BPDCN-specific gene expression program and apoptosis. High-throughput drug screening revealed that bromodomain and extra-terminal domain inhibitors (BETis) induced BPDCN apoptosis, which was attributable to disruption of a BPDCN-specific transcriptional network controlled by TCF4-dependent super-enhancers...

In this issue of Cancer Cell, Ceribelli et al. use functional genomic and chemical screening to reveal the existence of a TCF4/BRD4-dependent oncogenic regulatory network in blastic plasmacytoid dendritic cell neoplasm (BPDCN) and demonstrate that BPDCN cells are highly sensitive to therapeutic targeting of this novel dependency.

Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a clinically aggressive tumor derived from the precursors of plasmacytoid dendritic cells. It is a rare disease presenting across all ages with either skin or both skin and bone marrow involvement often conferring a poor prognosis. Though localized radiation has been used before, acute leukemia based regimens, remains the treatment of choice for induction of remission. Hematopoietic stem cell transplant, either autologous or allogeneic, is further required for attaining sustained remissions...

Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is an aggressive hematological malignancy with a poor prognosis that derives from plasmacytoid dendritic cells (PDC). No consensus for optimal treatment modalities is available today and the full characterization of this leukemia is still emerging. We identified here a BPDCN-specific transcriptomic profile when compared to those of acute myeloid leukemia and T-acute lymphoblastic leukemia, as well as the transcriptomic signature of primary PDC. This BPDCN gene signature identified a dysregulation of genes involved in cholesterol homeostasis, some of them being liver X receptor (LXR) target genes...

The incorporation of Internet resources and the use of social media among patients, clinicians, advocates, and researchers in the field of hematology and oncology are growing in importance. Utilization of online information sharing is rising, especially among those involved in rare blood cancer fields, which have generally featured a paucity of reliable, updated information. In particular, blastic plasmacytoid dendritic cell neoplasm (BPDCN), an uncommon, but highly aggressive hematologic malignancy, is one example of a cancer with limited information readily available to the general public...

Pediatric blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a rare hematological malignancy that has an extremely poor prognosis despite the use of intensive chemotherapy. Recently, treatment of BPDCN with bone marrow transplantation (BMT) using myeloablative conditioning has been reported to increase survival in adults. We report a 9-year-old girl with cutaneous BPDCN who was successfully treated with combination chemotherapy followed by BMT using reduced intensity conditioning (RIC), without any adverse complications...

Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a clinically aggressive tumor, which frequently presents as cutaneous lesions and subsequently progresses to bone marrow (BM) involvement and leukemic dissemination. BPDCN is a rare entity that belongs in the same class as acute myeloid leukemia-associated precursor neoplasms, according to the 2008 World Health Organization classification. The present study reported the case of a 26-year-old female who presented with evident thrombocytopenia, leukocytosis and anemia, but without skin lesions...

Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a rare haematological malignancy derived from the precursors of plamacytoid dendritic cells, with an aggressive clinical course and high frequency of cutaneous and bone marrow involvement. Neoplastic cells express CD4, CD43 (also termed SPN), CD45RA and CD56 (also termed NCAM1), as well as the plasmacytoid dendritic cell-associated antigens CD123 (also termed IL3RA), BDCA-2 (also termed CD303, CLEC4E) TCL1 and CTLA1 (also termed GZMB). The median survival is only a few months as the tumour exhibits a progressive course despite initial response to chemotherapy...

Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a rare and highly aggressive leukemia for which knowledge on disease mechanisms and effective therapies are currently lacking. Only a handful of recurring genetic mutations have been identified and none is specific to BPDCN. In this study, through molecular cloning in an index case that presented a balanced t(3;5)(q21;q31) and molecular cytogenetic analyses in a further 46 cases, we identify monoallelic deletion of NR3C1 (5q31), encoding the glucocorticoid receptor (GCR), in 13 of 47 (28%) BPDCN patients...

Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a rare aggressive myeloid neoplasm which shows a high rate of central nervous system (CNS) recurrence and overall survival (OS) of <1 year. Despite this, screening for CNS involvement is not routinely performed at diagnosis and intrathecal (IT) prophylaxis is not regularly administered in BPDCN. Here, we prospectively evaluated 13 consecutive BPDCN patients for the presence of CNS involvement by flow cytometry. Despite none of the patients presented with neurological symptoms, occult CNS involvement was detected in 6/10 cases evaluated at diagnosis and 3/3 studied at relapse/progression...

Myeloid neoplasms constitute one of the most common malignancies in adults. In most cases these proliferations initially manifest in the blood and marrow; however, extramedullary involvement may precede blood or marrow involvement in a subset of cases, making a definitive diagnosis challenging by morphologic and immunohistochemical assessment alone. Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a rare, aggressive entity that frequently presents in extramedullary sites and can show morphologic and immunophenotypic overlap with myeloid neoplasms...

Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a rare aggressive hematologic malignancy primarily found in adults, often carrying a poor prognosis. There are only 33 reported pediatric cases of BPDCN in the literature. Although standard treatment is not yet established for children, current literature recommends the use of high-risk acute lymphoblastic leukemia (ALL)-type chemotherapy. Recent studies, however, have explored the benefits of combining chemotherapy with stem-cell transplantation. Here, the authors present 2 cases of pediatric BPDCN treated with different modalities...
