摘要
Rationale:Trichosporon,an anamorphic fungus,proliferates under high humidity,causing serious opportunistic infections collectively called trichosporonosis.Among the Trichosporon species causing trichosporonosis are Trichosporon(T.)asahii,T.asteroides,T.cutaneum etc.Patient concerns:A 38-year-old Chinese male with severe aplastic anemia was admitted due to multiple joints pain,poor appetite,and right ankle swelling.One year earlier he had undergone allogeneic hematopoietic stem cell transplantation.Diagnosis:T.asahii infection and severe aplastic anemia.Interventions:Combined treatment of amphotericin B liposomes(55 mg/24 h)and voriconazole(200 mg/12 h)for 8 days.Outcomes:The symptoms of the patient’s ankle were relieved and effusion cultures showed no T.asahii.Lessons:To the best of our knowledge,T.asahii ankle cavity effusion infections are rare.Trichosporon infections may be attributed to risk factors such as improper long-term use of antimicrobials for an underlying disease(e.g.,anemia,hypoalbuminemia).Attention should be paid to prevent and control Trichosporon infections in order to avoid comorbidities.
