Schizophyllum commune
is widely distributed in the nature, but it rarely causes human infection. We have isolated this mould in a 46-year-old immunocompetent, non-diabetic patient with chronic sinusitis, previously treated with multiple antibiotics and topical steroid nasal drops with no response. Materials obtained from the nasal sinus during the endoscopic surgery, on KOH mount and histopathological study revealed broad septed hyaline hyphae. Growth on the Sabouraud′s dextrose agar and potato dextrose agar produced white moulds with microscopic and macroscopic characters of
S.
commune. Till date there are few reports of
S.
commune sinusitis in immunocompetent individuals Worldwide. This is the first reported case in India to the best of our knowledge.
