A Case of Blastic Plasmacytoid Dendritic Cell Neoplasm in a Child

Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a very rare hematological malignancy in children that is characterized by bruise-like skin lesions, with or without bone marrow involvement. Because the clinical course of BPDCN is highly aggressive and fatal in adults, allogeneic hematopoietic stem cell transplantation (HSCT) is recommended as the optimal treatment. Due to its rarity, the pediatric experience with BPDCN is limited and standard treatment has so far not been defined. We report a case of a 14-year-old boy with BPDCN involving the skin, bone marrow and lymph nodes. The patient was treated with high-risk group acute lymphoblastic leukemia protocol. He achieved a complete remission after induction chemotherapy and still maintains clinical remission without HSCT for 17 months after initial diagnosis. KCI Citation Count: 1
