Description
Summary:Trichosporon species are usually opportunistic pathogens. Disseminated trichosporonosis is uncommon but is increasingly reported with a high mortality rate, especially in immunocompromised patients. Although Trichosporon asahii and T. mucoides are known as the most common pathogens of disseminated trichosporonosis, cases of systemic infection due to T. inkin have been reported recently. However, no autopsy case of disseminated T. inkin infection has been reported. Herein is presented an autopsy case of disseminated trichosporonosis caused by T. inkin in a 30-year-old man with allogenic peripheral blood stem cell transplantation for acute myelocytic leukemia. In the present case, identification of T. inkin was performed with morphological, molecular biological and biochemical methods. It is difficult to make a diagnosis of Trichosporon infection on only histological examination; therefore, molecular biological and biochemical methods are needed in a diagnosis of disseminated trichosporonosis.
