Subcutaneous scedosporiosis: Report of two cases and review of the literature

Two cases of subcutaneous scedosporiosis, caused by Scedosporium apiospermum, are reported. Both patients had lesions localized in the forearm: a solitary ulceration in one and a sporotrichoid-like lesion in the other. The literature is reviewed

PULMONARY SCEDOSPORIOSIS

A case of a solitary pulmonary nodule due to Scedosporium apiospermum (Pseudallescheria boydii) is related. A review of the pertinent literature was done and, in addition, similar lesions caused by other opportunistic fungi are commented.

Scedosporium apiospermum EUMYCETOMA SUCCESSFULLY TREATED WITH ORAL VORICONAZOLE: REPORT OF A CASE AND REVIEW OF THE BRAZILIAN REPORTS ON SCEDOSPORIOSIS

We describe a case of white-grain eumycetoma caused by Scedosporium apiospermum in an immunocompetent host that was successfully treated with oral voriconazole, and we review the Brazilian reports on scedosporiosis.

Peritonitis by Scedosporium apiospermum in a patient undergoing continuous ambulatory peritoneal dialysis

A case of peritonitis due to Scedosporium apiospermum in a boy undergoing continuous ambulatory peritoneal dialysis is reported. The finding of suggestive tissual form of the fungus in the effluent hastened the diagnosis of the infection.

Respiratory tract intracavitary colonization due to Scedosporium apiospermum: report of four cases

Four cases of respiratory tract intracavitary colonization (fungus ball) due to Scedosporium apiospermum (teleomorph, Pseudallescheria boydii) are reported. The need for a careful search for anneloconidia, in order to establish the etiologic diagnosis in the clinical specimen by microscopy, is emphasized.

The opportunistic fungal pathogen Scedosporium prolificans: Carbohydrate epitopes of its glycoproteins

Isolated from the mycelium, of Scedosporium prolificans were complex glycoproteins (RMP-Sp), with three structurally related components (HPSEC). RMP-Sp contained 35% protein and 62% carbohydrate with Rha, Ara, Man, Gal, Glc, and GlcNH(2) in a 18:1:24:8:6:5 molar ratio. Methylation analysis showed mainly nonreducing end- of Galp (13%), nonreducing end- (9%),2-O-(13%), and 3-O-subst. Rhap (7%), nonreducing end-(11%), 2-O-(10%), 3-O-(14%), and 2,6-di-O-subst. Manp units (13%). Mild reductive P-elimination of RMP-Sp gave alpha-L-Rhap-(1-->2)-alpha-L-Rhap-(1-->3)-alpha-L-Rhap-(1-->3)-alpha-D-Manp-(1-->2)-D-Man-ol, with Man-ol substituted at O-6 with beta-D-Galp units, a related pentasaccharide lacking beta-D-Galp units, and beta-D-Galp-(1-->6)-[alpha-D-Manp-(1-->2)]-D-Man-ol in a 16:3:1 w/w ratio. Traces of Man-ol and Rha-ol were detected. ESI-MS showed HexHex-o1 and HCX(3-6)Hex-ol components. Three rhamnosyl units were peeled off successively from the penta- and hexasaccharide by ESI-MS-MS. The carbohydrate epitopes of RMP-Sp differ from those of the glycoprotein of Pseudallescheria boydii, a related opportunistic pathogen. (C) 2007 Elsevier B.V. All rights reserved.
