Transformación de síndrome mielodisplásico a leucemia linfoblástica aguda: 2 casos nuevos / Transformation of myelodysplastic syndrome to acute lymphoblastic leukemia: 2 new cases

RESUMEN

Los síndromes mielodisplásicos (SMD) son desórdenes clonales de las células hematopoyéticas, con riesgo variable de transformación a leucemia mieloblástica aguda. La evolución a leucemia linfoblástica aguda (LLA) es extremadamente rara, con muy pocos casos pediátricos. Este artículo describe 2 nuevos casos de SMD que progresaron a LLA, junto a una revisión de la literatura, observando un pronóstico similar a los adultos (AU)

ABSTRACT

Myelodysplastic syndromes (MDS) are clonal disorders of hematopoietic stem cells, with a variable risk of transformation to acute myeloid leukemia. Progression into acute lymphoblastic leukemia (ALL) is an extremely rare event, with very few cases published in children. In this report, we describe two cases of myelodysplastic syndromes that progressed to ALL. Moreover, we review previously reported cases of MDS transformation to acute lymphoblastic leukemia in the pediatric population whose prognosis seems to be similar to that for adults (AU)
