Malassezia species are components of the normal skin flora and can cause tinea (pityriasis) versicolor, round scaly patches of hypo- or hyperpigmented skin on the neck, chest, or upper arms. M. furfur causes catheter-related fungemia in premature neonates receiving IV lipids by central venous catheter. Topical creams and lotions for 2 weeks are effective in treating superficial Malassezia infections; fungemia caused by Malassezia species is treated with AmB or fluconazole, prompt removal of the catheter, and discontinuation of the lipid infusion.
