InvasiveScopulariopsis brevicaulisinfection in an immunocompromised patient and review of prior cases caused byScopulariopsisandMicroascusspecies

Scopulariopsis species and their Microascus teleomorphs are cosmopolitan fungi that are uncommonly associated with invasive disease. This report describes a case of fatal disseminated Scopulariopsis brevicaulis disease in a patient with diffuse large B cell lymphoma who underwent high-dose chemotherapy followed by a matched unrelated donor stem cell transplant. This case is compared with 32 prior cases of proven invasive Scopulariopsis (Microascus) infections reported in the literature. A focus of this report is the diagnostic methods utilized which included histopathology and culture with both micromorphologic and genotypic procedures employed to confirm the species identification.
