Post-transplantation laryngeal actinomycosis

A case of laryngeal actinomycosis occurred after bone marrow transplantation was reported. The patient was a 14-year-old girl who had a history of bone marrow transplantation for the treatment of acute lymphocytic leukemia 4month before the onset of the disease. She was referred to our hospital complaining persistent sore throat since 2weeks ago. Fiberscopic observation proved the presence of white tumor-like mass on her right arytenoid of the larynx. As CT image demonstrated that the mass was localized at the arytenoid region with central low-density area surrounded by granulation tissue, we underwent biopsy under local anesthesia.
