Appearance of ring sideroblasts in bone marrow during linezolid therapy

Abstract

A female patient with renal dysfunction developed thrombocytopenia after 2 weeks of linezolid treatment. Her bone marrow showed abnormal erythroblast morphology and abundant ring sideroblasts. No chromosomal abnormalities or other signs of myelodysplasia were seen in an early follow-up bone marrow aspirate, where the abnormal morphological findings had almost totally subsided.
