Management and treatment of Magnusiomyces capitatus (Geotrichum capitatum) pleural infection in a non-neutropenic patient with posaconazole. A new therapeutic opportunity?
Magnusiomyces capitatus may cause uncommon yet severe infections, especially in patients with haematologic disorders. Diagnosis may be difficult and time-consuming and newer approaches are required including the MALDI-TOF technique implemented with the detection of fungal antigens in the body fluids. The recommended treatment includes amphotericin B alone or in combination with flucytosine. We describe a case of a non-neutropenic patient with M. capitatus pleural infection, as identified by MALDI-TOF, positivity for galactomannan antigen in the BAL fluid, and successfully treated with oral posaconazole in single therapy
