Abstract
Fungi are widely implicated in chronic rhinosinusitis. Direct microscopic examination (DME) is used to confirm the biological diagnosis of fungal rhinosinusitis (FRS). Diagnostic sensitivity of DME is better than culture, however DME does not allow fungal species identification. In this study, we included 54 sinus samples demonstrating hyphae on DME. Direct sequencing was compared to culture for the identification of the fungal species. Sequence analysis identified fungi in 81.5% of cases while culture was positive in only 31.5%. The most common genus was Aspergillus and the identified species belonged to section Fumigati or to section Flavi. Among other fungi identified by sequence analysis, Schizophyllum commune was present in three samples attesting to the importance of this Basidiomycetes in FRS. Our results clearly demonstrate the superiority of sequencing compared to culture when performed on specimens with hyphal elements at DME, and contributes to the epidemiological knowledge of fungi involved in FRS.

Med Mycol 2015; 54:301-9.

Abstract
Schizophyllum commune is a common basidiomycete fungus that is rarely involved in human disease. The medical records of patients operated on for fungal rhinosinusitis (FRS) in two University Hospitals between 2012 and 2014 were reviewed. Within the two-year survey, six female, and notably no male, patients were diagnosed with S. commune rhinosinusitis. Mean age was 44.6 years at diagnosis (30 to 68 years). Mean time between onset of symptoms and diagnosis was 8.5 months (2 to 12 months). All six patients were immunocompetent and had no particular host factor for FRS. S. commune was identified using MALDI-TOF mass spectrometry and identifications were confirmed via DNA sequence analysis. Chronic invasive fungal rhinosinusitis was diagnosed in three of our six patients. Based on histological findings, antifungal treatment was delivered in association with surgery. The basidiomycete fungus S. commune is an emerging cause of rhinosinusitis probably as a direct consequence of the recent technological progress in fungal identification methods (DNA sequencing and MALDI-TOF mass spectrometry).

Schizophillum commune causing sinusitis with nasal polyposis in the sub-Himalayan region: first case report and review. Mycopathologia 2013; 177:103-10.

Abstract
Schizophillum commune is an environmental fungus rarely causing human infections of diverse nature. Sinusitis occurs in immunocompromised persons and seldom in healthy subjects. Though easily isolated, the lack of awareness of its virulence is a bottleneck in the diagnosis of this infection. We report the first case of S. commune sinusitis with nasal polyps in an immunocompetent male from the sub-Himalayan region. The computerized tomography scan findings established the clinical diagnosis, and causative agent was confirmed as S. commune. A white, woolly mold with septate, hyaline hyphae and characteristic spicules but unclamped connections suggested a monokaryotic isolate. Patient was treated successfully with fiberoptic endoscopic sinus surgery, and no antifungal therapy was instituted. There was no recurrence at review after 1 year.

Abstract
Fungal rhinosinusitis is being recognized and reported with increasing frequency over the last two decades worldwide. Intracranial extension is the most dreaded complication of fungal sinusitis with high mortality rates. We report a case of chronic rhinosinusitis in a 55-year-old diabetic male, caused by Fusarium species. The patient was diagnosed as a case of chronic left maxillary sinusitis with cavernous sinus thrombosis. The sinus lavage showed fungal elements on direct microscopic examination and culture revealed growth of Fusarium species within 4 days of incubation. Conservative therapy with IV amphotericin B resulted in favorable outcome of the patient. This is an extremely rare case where cavernous sinus thrombosis occurred as a complication secondary to Fusarium species rhinosinusitis.
