Until recently, Malassezia furfur was thought to be a pathogen only in tinea versicolor. More recently, this lipophilic yeast has been recovered from sick neonates with catheter-related infections. Malassezia fungemia was studied in seven patients, and the salient features of this infection in patients described in the literature were reviewed. Major risk factors include prolonged hospitalization, the presence of central venous catheters, and the use of intravenous fat emulsions. It is difficult to identify specific manifestations of fungemia in these complex cases occurring in patients with severe underlying disease; however, neonates often present with the signs and symptoms of sepsis and thrombocytopenia, whereas fever may be the only manifestation in adults. Some patients are asymptomatic. When symptoms are present, they resolve upon removal of the colonized catheter. The role of the lipophilic nature of Malassezia in the pathogenesis of infection is apparent from the ability of intravenous fat emulsions to support the growth of the fungus in vitro. A special solid medium that can be used to determine the true prevalence of malassezia fungemia has been devised. M. furfur must be considered in the differential diagnosis of opportunistic infections in patients receiving central hyperalimentation and should be sought by the culture of blood on appropriate medium.

A 15-month retrospective survey of 507 admissions to a neonatal intensive care unit revealed 8 patients from whom Malassezia pachydermatis was isolated from one or more clinical specimens. The fungus was cultured from blood (four patients), central venous catheter tips (three patients), urine (four patients), cerebrospinal fluid (one patient), eye discharge (one patient), ear discharge (one patient) and tracheal aspirate (one patient). Seven of the eight infants displayed an episode of one or more of the following symptoms: apnea, bradycardia, temperature instability and hepatosplenomegaly. These episodes were temporally related to recovery of M. pachydermatis from clinical specimens. The seven symptomatic infants had received multiple antibiotics as well as long term hyperalimentation, including lipids, by infusion through deep vein catheters; the single asymptomatic infant did not. These data suggest an association between M. pachydermatis and the febrile systemic syndrome of neonates recently described for extracutaneous infections due to Malassezia furfur.

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.
