Schizophyllum commune sinusitis in an immunocompetent host.

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.

Basidiomycosis: a review of the literature

As basidiomicoses, infeccoes fungicas provocadas por basidiomicetos vem sendo registradas cada vez com maior frequencia na literatura medica, principalmente apos o advento da AIDS/SIDA, em 1981. Os basidiosporos desses fungos, espalhados na atmosfera e veiculados atraves do vento ou de correntes aereas, atingem por via nasal os seios maxilares, provocando quadros de sinusite cronica, na maioria das vezes. Do escarro tambem tem sido isolados basidiomicetos, principalmente o Schizophyllum commune. Lesoes da mucosa da boca, abscessos cerebrais, onicomicoses e endocardites ja foram descritas, aumentando o interesse dos micologistas e infectologistas para este tipo de micose profunda. O presente trabalho assinala, ao lado dos quadros de micetismo, processos infecciosos provocados por basidiomicetos, a exemplo do Schizophyllum commune, Ustilago maydis (=Ustilago zeae) e Coprinus cinereus

Aislamiento de Schizophyllum commune en Panama / The isolation of Schizophyllum commune in Panama

The authors report the isolation of the basidiomycete Schizophyllum commune in two enclosed areas of healthy facilities in the city of Panama. The growth occurred in Sabouraud's agar as a white mycelium which gradually rose above the surface of the culture medium until it became a fan-shaped basidiocarp. This basidiomycete is found in environmental samples, but since there have been reports of its role in pathologic processes it should be included in the etiologic differential diagnosis in some patients and clinical laboratory must identify it and not discard it as a [quot]contaminant[quot]
