This paper reports a pediatric patient with acute myeloid leukemia (AML) who developed bloodstream infection (BSI) caused by Trichosporon dohaense (T. dohaense). The pathogen in the blood culture of this case could not be identified by VITEK MS mass spectrometer; it was mistakenly identified as T.asahii by the VITEK Ⅱ YST system, and was ultimately accurately identified as T. dohaense through molecular sequencing. The (1-3)-β-D-glucan test (G test) result for this pediatric patient was within the normal range. The patient recovered and was discharged after active clinical antifungal treatment. Therefore, for T. dohaense BSI patients with granulocytopenia, it is necessary to actively administer antifungal treatment in clinical practice, carefully interpret G test results, and further strengthen the understanding of this rare fungus.
