Blastic plasmacytoid dendritic cell neoplasm is a rare hematologic neoplasm characterized by cutaneous, hematologic, and central nervous system (CNS) involvement with poor prognosis. Diagnosis is made by flow cytometry, although there are no specific markers, making its diagnosis challenging. So far, with the available evidence, acute lymphoid leukemia-type schemes and consolidation with allogeneic transplant seem to become the first-line therapy. With its characterization, new therapies directed toward CD123 and the anti-apoptotic protein Bcl-2 have appeared to prolong the survival of these patients. We present a case of a 27-year-old male patient diagnosed with blastic plasmacytoid dendritic cell neoplasm with unusual CNS manifestations and without skin involvement who achieved complete remission with venetoclax and improvement of neurological symptoms, making him a candidate for hematopoietic stem cell transplant.
Se describe el caso de una mujer de 68 años, con muy alto riesgo cardiovascular, quien consultó por cianosis en los dedos de los pies, asociada a síntomas neurológicos focales transitorios de 5 días de evolución. Se hospitalizó con la impresión diagnóstica de síndrome del dedo azul e isquemia crítica arterial de miembros inferiores de posible origen embólico. Luego de un procedimiento endovascular, presentó deterioro neurológico súbito y se documentaron múltiples infartos cerebrales y falla renal aguda. En la biopsia de los dedos afectados se observaron cristales de colesterol en el interior de los vasos sanguíneos. Con base en el caso se presenta una corta revisión del síndrome del dedo azul y su principal causa: la ateroembolia.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
