CONTEXTO: Mielofibrose é uma neoplasia maligna rara que pode se desenvolver como doença primária, sendo uma doença mieloproliferativa crônica caracterizada pela falha da medula óssea e proliferação clonal de células mieloides associada com excesso de fibras de reticulina e/ou colágeno, e algum ...

BACKGROUND: Philadelphia-negative myeloproliferative neoplasms (Ph-MPN) are chronic hematological disorders characterized by the overproduction of one or more mature myeloid blood cell lineages. Classical Ph-MPN are polycythemia vera (PV), essential thrombocytopenia (ET) and primary myelofibrosis (PMF). ...

La panmielosis aguda con mielofibrosis (PMAF) es un raro desorden hematológico, definido como un subtipo de leucemia aguda. Se reporta un paciente masculino de 31 años de edad con historia de decaimiento marcado, fiebre vespertina y gingivorragia. El examen físico muestra palidez cutáneo mucosas, esp...
Abstract Background and objective: in the global scientific literature, the frequency of JAK2 is highly heterogenous in chronic myeloproliferative neoplasms. The objective of this study was to analyze the prevalence of the JAK2 mutation in primary myelofibrosis (PMF) and compare it according to the dete...
ABSTRACT Background: The classical BCR-ABL1-negative myeloproliferative neoplasms (MPNs) are Polycythemia Vera (PV), Essential Thrombocythemia (ET) and Primary Myelofibrosis (PMF). In developing countries, there are few reports that truly reveal the clinical setting of these patients. Therefore, we aime...
Abstract Introduction Ruxolitinib has been approved for the treatment of myelofibrosis (MF). In this study, we present safety and efficacy findings from an analysis of 104 patients with intermediate- and high-risk MF in a Brazilian cohort of the JUMP study who received treatment with ruxolitinib. Metho...
Resumen Introducción: la carga sintomática de pacientes con neoplasias mieloproliferativas crónicas Filadélfia negativas (NMC-PhN) afecta la calidad de vida (CV). Existen escalas para evaluar la magnitud de los síntomas, una de ellas, MPN-SAF-10. En nuestra región existe escasa información sobre ...
La Dermatosis neutrofílica de las manos es consi-derada una variante localizada acral del Síndrome de Sweet, más frecuente en mujeres y principal-mente asociada a enfermedades hematológicas. Las lesiones aparecen como pápulas, vesículas, nó-dulos, placas, úlceras y ampollas, prin...
Myelofibrosis (MF) is characterized by increased circulating hematopoietic progenitor cells (HPCs), abnormal cytokine levels, and the survival advantage of neoplastic progenitors over their normal counterparts, which leads to progressive disappearance of polyclonal hematopoiesis. CD47 is a surface glycop...
