Abstract:
A blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a cutaneous lymphoma derived from a plasmacytoid dendritic precursor cell that exhibits aggressive clinical behavior. Herein, we report a 46-year-old woman with a complaint of a painless nodule on the back, associated with pruritus. The nodule grew and new growths appeared over six months of evolution. The histopathological examination of one of the left upper limb lesions showed a dense lymphoid cell infiltrate with atypia in the superficial and deep dermis. Immunohistochemistry showed positivity for CD45, S-100 protein, CD123, and TCL 1. About two months after the initial evaluation, the patient was admitted to the Emergency Hospital of Marituba-PA with dyspnea. She progressed to cardiorespiratory arrest and death within 12 hours of admission. There is still no consensus for the treatment of BPDCN. Intensive therapy for acute leukemia can be useful, but allogeneic bone marrow transplantation has a greater chance of long-term survival.
