First case of invasive Magnusiomyces capitatus infection in Slovakia

Abstract

Magnusiomyces capitatus (previously known as Geotrichum capitatum or Blastoschizomyces capitatus or Trichosporon capitatum) is a rare cause of fungal infection in immunocompromised patients. Most of these cases (87%) have been reported from the Mediterranean region, as it is extremely rare to recognize it in other regions. Here we report a first case of disseminated M. capitatus infection in Slovakia. The patient – 19 year old woman with myelodysplastic syndrome was diagnosed with M. capitatus fungemia after allogeneic stem cell transplantation. The infection occurred despite antifungal prophylaxis with micafungin, which was in vitro sensitive to the yeast. The treatment according to minimal inhibitory concentrations (micafungin, voriconazol) and granulocyte transfusions were administered. M. capitatus was cleared out from the bloodstream. However, patient died of multiple organ failure. Autopsy showed multiple lesions in organs, but did not prove presence of yeast by histopathology. M. capitatus was confirmed by polymerase chain reaction from all tested organs: heart, brain, lungs, spleen, liver and kidneys. We present the post mortem pictures showing the yeast lesions in affected organs. 2012 Elsevier Ltd. All rights reserved.
