Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a rare and aggressive tumor that develops from plasmacytoid dendritic cell precursors and usually affects the skin and bone marrow.
A case study of a 30-year-old male patient highlights skin lesions filled with undifferentiated blast-like cells, identifiable by specific markers but not by B-cell or T-cell indicators.
Timely diagnosis and a multidisciplinary treatment approach are critical to prevent the disease's progression and improve patient outcomes, as misdiagnosis can lead to severe complications.
