Objective: To explore the clinical manifestation, pathological features and treatment regimen of blastic plasmacytoid dendritic cell neoplasm (BPDCN).
Methods: The clinical and pathologic features, diagnosis, treatment and prognosis of 5 BPDCN patients were analyzed retrospectively.
Results: 5 patients had skin lesions, and bone marrow involvement. The immunohistochemical staining showed that the CD56 expression was observed in 5 patients, CD4 and CD123 in 4 patients, and CD43 expressed in 3 patients. After initial treatment, 3 patients achieved complete remission and 1 patient did not. One patient showed disease progression after partial remission for 1 month. Two young patients underwent sibling allo-PBHSCT, and then achieved long-term survival.
Conclusion: BPDCN often presents skin lesions as the first symptom, moreover, soft tissues, lymph nodes and bone marrow were involved, which suggested the disease progresses. There is currently no uniform treatment protocol for this disease. Active allogeneic peripheral blood hematopoietic stem cell transplantation in the CR1 phase for appropriate patients may increase their chances for long-term survival.

Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is an aggressive orphan hematopoietic malignancy characterized by cutaneous and systemic hematologic involvement. BPDCN is frequently misidentified, but early, accurate diagnosis is critical to extending patient survival using tagraxofusp, a first-in-class CD123-targeted therapy, and increasing their chances of receiving a potentially curative stem cell transplantation. Cases of BPDCN in countries of the Gulf Cooperation Council are lower than the extrapolated incidence from other geographic locations due to lack of awareness of key diagnostic features, lack of consensus on the minimal phenotype for diagnosis, and lack of local immunohistochemistry testing facilities, contributing to underdiagnosis in this region.

Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a very rare and aggressive hematologic malignancy, arising from plasmacytoid dendritic cells (pDCs). BPDCN frequently has, at least initially, exclusively cutaneous presentation. We present a 45-year-old woman with a 3-month history of rapidly evolving violaceous patches, infiltrated plaques, and bruise-like tumefactions, disseminated on her face and upper trunk.

Blastic plasmacytoid dendritic cell neoplasm(BPDCN)is an extremely rare invasive tumor with poor prognosis.The common clinical manifestations of BPDCN include skin injury,bone marrow involvement,and tumor cell spread.BPDCN is often misdiagnosed as other diseases and its diagnosis often requires a combination of clinical manifestations,imaging,histology,and immunophenotyping.

Article Synopsis
- Chronic myelomonocytic leukemia (CMML) is a complex blood cell disorder that combines poorly functioning and overproducing blood cells, leading to various symptoms.
- The case study focuses on a 71-year-old man with severe CMML who experienced skin nodules that improved with treatment but later recurred, while avoiding progression to acute leukemia.
- The findings emphasize the importance of close monitoring and flexible treatment approaches for patients with CMML, especially those with skin involvement.
