Abstract
Candida nivariensis is a cryptic fungal species classified within the Candida glabrata complex. It was described for the first time in 2005 by the means of DNA sequencing. We report a rare case of C. nivariensis deep-seated infection occurring in a 77-year-old man hospitalized for cysto-prostatectomy. Phenotypic testing based on the direct examination and the macroscopic features of the in vitro culture initially suggested C. glabrata species, while MALDI-TOF mass spectrometry enables correct identification. The isolate was found resistant to fluconazole, like in almost 20% of the reported cases. Herein, we present our practical strategy to reliably characterize this rare cryptic species. To date, MALDI-TOF mass spectrometry-based analysis showed very good results for such a purpose.

Abstract
BACKGROUND Mucormycosis are rare fungal infections occurring chiefly in the lung or the rhinocerebral compartment, particularly in patients with immunodeficiency or mellitus diabetes. We report the case of an elderly patient with cutaneous mucormycosis caused by Rhizopus microsporus. PATIENTS AND METHODS An 89-year-old man presented a skin lesion of the forearm rapidly becoming inflammatory and necrotic. The patient had been treated for 2months with oral corticosteroids for idiopathic thrombocytopenia. Histological and mycological examination of the skin biopsy revealed the presence of a filamentous fungus, R. microsporus. The outcome was unfavorable, despite prescription of high-dose liposomal amphotericin B. DISCUSSION Mucormycosis are infrequent opportunistic infections caused by angio-invasive fungi belonging to the Mucorales order. Cutaneous presentations are rare, and in rare cases the species R. microsporus is isolated in clinical samples. Diagnosis is based on histological examination highlighting the characteristic mycelium within infected tissue, together with ex vivo mycological identification using morphological and molecular methods. Treatment consists of liposomal amphotericin B combined with debridement surgery. CONCLUSION R. microsporus is a marginal fungal species rarely isolated in clinical practice, and even less in dermatology departments. This clinical case report highlights the severity of infection with this fungus, particularly in the absence of early surgery.
