Reduced Intensity Allogeneic Stem Cell Transplant for Treatment of Blastic Plasmacytoid Dendritic Cell Neoplasm
نویسندگان
چکیده
Blastic plasmacytoid dendritic cell neoplasm is a rare, aggressive tumor characterized by skin and/or marrow infiltration by CD4(+) CD56(+) cells. Historically, the tumor was variably thought to arise from either monocytes, T cells or NK cells giving rise to terms such as CD4(+)/CD56(+) acute monoblastic leukemia, primary cutaneous CD4(+)/CD56(+) hematodermic tumor and blastic NK-cell lymphoma. Whilst considerable progress has been made in understanding the histogenesis, the best modality of treatment remains to be defined. We are therefore reporting this case which was successfully treated with a T-deplete allogeneic transplant and the patient is currently alive and in remission 4 years post transplant.

Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a rare hematodermic myeloid malignancy that is known to be derived from plasmacytoid dendritic cells which are characterized by expression of CD4, CD56, and more specific markers such as CD123. Here, the authors present three cases of BPDCN diagnosed in the past two years and address different available diagnostic modalities such as morpho...

Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is an aggressive myeloid neoplasm derived from plasmacytoid monocytes. The most common presentation involves cutaneous manifestations, which are often accompanied by bone marrow involvement. The tumor cells reveal an immature blastic appearance and diagnosis is based on the expression of cluster of differentiation (CD)4 and CD56. The literatu...

Blastic Plasmacytoid Dendritic Cell Neoplasm (BPDCN) is a rare and aggressive malignancy that usually presents with diffuse cutaneous lesions. While a favorable response to therapy occurs in a majority of cases, a sustained long-term response is uncommon. Most patients subsequently relapse within a year. In the following report, we present the case of a 41-year-old woman who has not displayed m...
