Comprehensive metagenomic analysis of blastic plasmacytoid dendritic cell neoplasm.

ABSTRACT: Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a hematologic malignancy believed to originate from plasmacytoid dendritic cells (pDCs), the immune cells responsible for producing type 1 interferons during infection. Nearly all patients with BPDCN have prominent skin involvement, with cutaneous infiltration occupying the dermis and subcutis. One half of patients present with BPDCN cells only in the skin, with no evidence of disease elsewhere. Because normal pDCs are rare or absent in cutaneous sites, and they only traffic to the skin after activation by pathogen or inflammation, our aim was to determine if a microorganism is associated with BPDCN. We performed RNA sequencing in BPDCN skin and bone marrow, with cutaneous T-cell lymphoma (CTCL) and normal skin as controls. GATK-PathS
