Infections in immunocompromised children can stem from bacteria, fungi, viruses, or protozoa, but most importantly, from the host's endogenous bacterial flora. Disseminated infection caused by Trichosporon species is one of the emerging mycoses in neutropenic patients, particularly when they are treated for haematological malignancy with cytotoxic and immunosuppressive chemotherapy. We report a 15-year-old boy with acute lymphoblastic leukaemia, whose Trichosporon mucoides infection was successfully treated with lipid complex amphotericin B plus 5-fluorocytosine.
