Could Candida dubliniensis be involved in lung fungus balls?

We describe a case of cavitary pneumonia due to Candida dubliniensis along with fungemia due to Candida kefyr in a leukemic patient. This is the first case of C. dubliniensis isolated in our laboratory. The identification was performed by phenotypic and molecular methods such as thermotolerance test, carbohydrate fermentation and polymerase chain reaction.
