Abstract
BACKGROUND
Blastic plasmacytoid dendritic cell tumor (BPDCN) is a rare and highly invasive lymphohematopoietic tumor that originates from plasmacytoid dendritic cells. BPDCN has an extremely poor prognosis. Skin lesions are usually the first manifestation of BPDCN, although the tumor may also invade the bone marrow, lymph nodes, peripheral blood, and other parts of the body, leading to several other manifestations, requiring further differentiation through skin biopsy and immunohistochemistry.
CASE SUMMARY
In the present paper, the cases of 2 patients diagnosed with BPDCN are discussed. The immunohistochemistry analysis of these 2 patients revealed positivity for CD4, CD56, and CD123. Currently, no standard chemotherapy regimen is available for BPDCN. Therefore, intensive therapy for acute lymphoblastic leukemia was applied as the treatment method for these 2 cases.
CONCLUSION
Although allogeneic bone marrow transplantation could be further effective in prolonging the median survival the ultimate prognosis was unfavorable. Future treatment modalities tailored for elderly patients will help prolong survival.
Core Tip: This article reported on 2 cases of blastic plasmacytoid dendritic cell tumor (BPDCN) patients diagnosed and treated in our hospital, describing clinical manifestations, laboratory examination, and treatment process. A summarization of the current literature, combined with the experience of these 2 patients, allowed for our reasoned overall conclusions. Based on the 2-patient experience, BPDCN as a hematologic malignancy has a very poor prognosis. Treatment with acute lymphoblastic leukemia chemotherapy is effective in some way. Venetoclax, a BCL-2 inhibitor, can partially subside skin lesions. Unless stem cell transplantation is used, there is no significant improvement in overall survival time.
