Abstract

CASTRO, Luz Ángela; ALVAREZ, María Inés  and  MARTINEZ, Ernesto. Case report of Schizophyllum commune sinusitis in an immunocompetent patient. Colomb. Med. [online]. 2010, vol.41, n.1, pp.71-75. ISSN 1657-9534.

Schizophyllum commune is a basidiomycete fungus with broad distribution in nature; however, it is a rare cause of infectious disease. We report the isolation of this mould in a 46 year-old immunocompetent patient with chronic sinusitis previously treated with multiple antibiotics and topical nasal steroids. Material obtained via a left maxillary sinus antrostomy showed septate hyaline hyphae with clamp connections on direct examination with KOH and histopathological studies. Further growth on Sabouraud agar produced a white mould that, based on its microscopic and macroscopic characteristics, was identified as S. commune. Despite its low frequency, this fungus should be considered a possible pathogen, particularly in samples obtained from paranasal sinuses.

Keywords : Basidiomycete; Sinusitis; Schizophyllum commune; Diagnostic; Itraconazole.
