Refractoriness to platelet transfusion is a complex process that can be due to a diverse array of etiologies. We report a case of refractoriness in a patient with acute myelogenous leukemia (AML) and the diagnostic challenge associated with it.

Diagnostic evaluation revealed multiple potential underlying etiologies and contributing factors, with alloimmunity to HLA antigens determined to be the most probable cause after thorough laboratory investigation.
INTRODUCTION The term 'platelet refractorinesses' used to describe a post-transfusion increment in a patient's platelet count that is less than expected. Inadequate responses to platelet transfusion are not uncommon particularly [...]
