[Septicemia caused by Malassezia furfur].

A case of septicaemia caused by Malassezia furfur in a newborn patient receiving intravenous nutrition is presented. M. furfur, the well known cause of pityriasis versicolor, is a strict lipophilic yeast, with predilection for indwelling catheters conducting lipid solutions. Since the diagnosis of M. furfur is hampered by the slow growth and the requirement of lipid containing growth media, one must keep the organism in mind when signs of septicaemia occur in a patient receiving parenteral nutrition, especially in premature infants.
