ABSTRACT
Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a rare and aggressive hematological malignancy derived from precursors of plasmacytoid dendritic cells. The majority of patients initially respond to multi-agent chemotherapy, though most relapse within a year and the prognosis is very poor. We report a 67-year-old man with erythema on the right chest and a nasopharyngeal mass. Histological examination revealed a mass of tumor cells expressing CD4, CD56, and CD123, but neither CD3 nor CD20. He was diagnosed with BPDCN. Bone marrow involvement was not seen at diagnosis. He achieved complete remission (CR) with CHOP-like chemotherapy. After 1 year, he relapsed with a cutaneous tumor on the head, a nasopharyngeal tumor, and massive bone marrow involvement. Relapsed BPDCN is generally resistant to chemotherapy and the prognosis is dismal. However, he was successfully treated with biweekly CHOP therapy and achieved a second CR lasting 16 months.
