Primary oral Penicillium marneffei infection diagnosed by PCR-based molecular identification and transmission electron microscopic observation from formalin-fixed paraffin-embedded tissues

摘要

We report a case of primary oral Penicillium marneffei infection in a 39-year-old man without HIV infection. Although fungal culture was negative, the patient was finally confirmed to have P. marneffei infection by PCR-based molecular identification and transmission electron microscopic observation from formalin-fixed, paraffin-embedded tissues. The patient was cured with taking itraconazole for 3 months.
