Objective: To summarize and analyze the clinical features of blastic plasmacytoid dendritic cell neoplasm (BPDCN), so as to enhance the understanding of this disease.
Methods: The clinical manifestations, immunophenotype, pathological features, treatment and prognosis of 11 cases of BPDCN were retrospectively analyzed.
Results: Among the 11 patients diagnosed with BPDCN, there were 8 males and 3 females, with a median age of 44 (6-81) years.

Background/aim: Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a rare and highly aggressive hematologic cancer which is difficult to diagnose and has a lot of overlapping features with other diseases, particularly acute myeloid leukemia (AML). BPDCN shares several immunophenotypic markers with AML, such as CD4, CD56, CD123, and HLA-DR, stating the importance of having extending panel of specific immunohistochemical (IHC) markers.
Case Report: This report details a case of CLL who presented with worsening symptoms of recurrent infections and leukocytosis.

Chronic myelomonocytic leukemia (CMML) is a myelodysplastic/myeloproliferative neoplasm characterized by peripheral blood monocytosis and bone marrow dysplasia. In approximately one-fourth of cases, CMML can demonstrate progression to acute myeloid leukemia (AML), referred to as AML ex CMML. We present a 58-year-old woman with a past medical history of idiopathic thrombocytopenic purpura (ITP) who demonstrated 24% bone marrow blasts on a repeat biopsy obtained two years after being diagnosed with CMML.

Acute myeloid leukemia (AML) remains a dismal disease with poor prognosis, particularly in the relapsed/refractory (r/r) setting. Chimeric antigen receptor (CAR) therapy has yielded remarkable clinical results in other leukemias and thus has, in principle, the potential to achieve similar outcomes in r/r AML. Re-directing the approved CD19-specific CAR designs against the myeloid antigens CD33, CD123 or CLEC12A has occasionally yielded morphological leukemia-free states (MLFS) but has so far been marred by threatening myeloablation and early relapses.

CAR T-cell therapy has remarkably succeeded in treating lymphoblastic leukemia. However, its success in AML remains elusive due to the risk of on-target off-tumor toxicity to hematopoietic stem and progenitor cells (HSPC) and insufficient T-cell persistence and longevity. Using a SynNotch circuit, we generated a high-precision "IF-THEN" gated logical circuit against the combination of CD33 and CD123 AML antigens and demonstrated anti-tumor efficacy against AML cell lines and patient-derived xenografts.
