It is difficult to identify this bacterium through conventional Gram-staining and biochemical methods due to an amorphous Gram stain appearance after 24 h culture and its relatively fastidious and slow growth giving weak and\/or delayed reactions in biochemical tests. It is often misidentified as other bacteria including <jats:italic>Haemophilus<\/jats:italic> spp., <jats:italic>Pseudomonas aeruginosa<\/jats:italic>, or <jats:italic>Sphingomonas paucimobilis.<\/jats:italic> False identification may delay the therapy of the patients and even endanger the patient\u2019s life. Here, we report a case of a 34-year-old man with acute lymphoblastic leukemia infected by <jats:italic>F. philomiragia<\/jats:italic>, which was almost misdiagnosed. This case describes our identification of a patient with a systemic <jats:italic>F. philomiragia<\/jats:italic> infection.
