Malassezia furfur fungaemia in a ventilator-dependent patient without known risk factors.

Malassezia furfur is the lipophilic yeast which causes tinea versicolor and is an uncommon cause of fungaemia. It usually occurs in the context of hyperalimentation with lipid emulsion, immunosuppression, or the presence of a central venous catheter. We report a case of a ventilator-dependent patient who developed Malassezia furfur fungaemia in the absence of these known risk factors. A likely risk factor in this patient was receipt of multiple courses of broad-spectrum antibiotics. This case highlights the importance of recognising Malassezia furfur as a cause of fungaemia, as well as the need for special culture techniques to aid identification.
