Real-world management of blastic plasmacytoid dendritic cell neoplasm at an academic center with a broad regional referral base.

BPDCN is an aggressive myeloid malignancy characterized by unique expression of CD123, CD4, CD56, CD303, CD304, TCL1 and TCF4. The development of tagraxofusp, a CD123-directed cytotoxin, has revolutionized BPDCN treatment, especially for patients unfit for chemotherapy. While most patients respond to frontline tagraxofusp, there are challenges associated with treatment. In this case series, we describe our institutional experience treating BPDCN both pre- and post-tagraxofusp approval. We summarize six cases, the majority of which occurred in elderly patients, and highlight unique challenges of treating BPDCN at a center that serves a large rural/frontier area with variable access to specialty care.
