Scedosporium boydii finding in an immunocompromised patient and review of the literature Rev. Iberoam. Micol. (IF 1.9) Pub Date : 2024-02-07 Silvana Ramadán, Hernán Dalmaso, Alicia Luque, Maximiliano Sortino, María Luján Cuestas, Katherine Hermida Alava, Diego Bertola, Lucía Bulacio
Scedosporiasis is an emerging mycosis that has gained importance in recent years due to its worldwide prevalence. It is caused by species of the complex. These species can cause opportunistic infections in immunocompromised patients and, occasionally, in immunocompetent patients as well. The high intrinsic antifungal resistance make these infections difficult to manage. The objective of this study
