Prolonged fever and splenic lesions caused by Malassezia restricta in an immunocompromised patient

Malassezia species are commonly found on human skin as commensals but can cause invasive infections in premature infants and immunocompromised hosts. Due to their fastidious growth, diagnosis of Malassezia infections can prove challenging. Molecular techniques can aid in diagnosis and treatment of invasive infections. We describe the case of a pediatric oncology patient with splenic lesions secondary to Malassezia restricta.
