is an opportunistic multidrug-resistant pathogen that was first isolated in 2009 and has since been reported from about 30 countries. In Saudi Arabia, only four cases of have previously been reported; here, we report two new cases of this infection. Both patients were polymorbid and had long hospitalization periods with recurrent intensive care unit (ICU) admissions. The findings of the tissue/blood cultures and antimicrobial therapy protocols are explained in the case report. Urine culture in both cases was positive for , and the colonies grew well at 42°C. The fungal isolates were confirmed by matrix-assisted laser desorption ionization time-of-flight mass spectrometry. The first patient was treated with the recommended dose of caspofungin, but he passed away. The second patient was also planned to be treated with caspofungin, but he passed away before the treatment could be initiated. The present cases further corroborate signs of a growing number of reports of in patients with high-risk factors, such as hospitalization in ICU, multiple chronic conditions and prolonged antimicrobial treatment exposure. It also highlights the need for hospitals to further improve their infection control practices to prevent nosocomial infections such as .
