Abstract
Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a rare hematodermic neoplasm which typically presents with skin infiltrates with or without lymphadenopathy and bone marrow involvement. No standard of care exists for this aggressive disease and prognosis is particularly poor. Here, we present our experience with nine BPDCN patients diagnosed at our institution between 2005 and 2012. BPDCN patients were identified in the databases at the Department of Hematology and Oncology, the Department of Dermatology, and the Institute of Pathology at the Otto-von-Guericke-University Magdeburg. There were six male and three female patients with a median age at diagnosis of 66 years. Sites involved were skin (five cases), lymph nodes (five cases), and bone marrow (five cases). Treatments varied from single agent chemotherapy to polychemotherapy and allogeneic stem cell transplantation for consolidation. The three patients that were treated with acute leukemia-type induction therapy followed by allogeneic stem cell transplantation (one after standard conditioning and two after reduced intensity conditioning using fludarabine in combination with thiotepa) achieved sustained remissions and are alive with a follow-up of 8, 35, and 41 months. In contrast, median survival in the less intensively treated patients was only 9.5 (range 1 to 29) months.
