18 de dic. de 2023 · Dysplastic changes associated with medications may be seen in all bone marrow lineages and may be accompanied by macrocytosis, reduced neutrophil lobulation, and cytopenias. In most cases, dysplastic changes are reversible over a period of weeks after reduction or discontinuation of the offending medication.
The cornerstone of the diagnosis is bone marrow biopsy, where dysplastic changes in one or more cell lines, the presence of ringed sideroblasts, the number of blasts and the cytogenetic study make it possible to classify this disease in six different subtypes.
A bone marrow biopsy with aspirate to assess marrow cellularity, dysplasia, number of blasts and underlying fibrosis is requisite. Additional flow cytometry and MK are also vital [ 6 ]. In approximately 90% of patients with MDS, the bone marrow examination is overtly hypercellular and dysplasia affecting erythroid or megakaryocytic lineages can ...
15 de may. de 2008 · Examination of the bone marrow (aspirate, biopsy, cytogenetics, and flow cytometry) and the peripheral blood should reveal the morphologic features of the disease and exclude other conditions that can lead to cytopenias.
24 de oct. de 2013 · Bone marrow biopsy may aid the exclusion of other clinical conditions presenting with cytopenia and provide information on marrow cellularity, megakaryocyte component, blast compartment, bone marrow fibrosis, and the presence of nonhematologic cells, such as metastases.
