Nattrassia mangiferae formerly known as Hendersonula toruloidea,is a phaeoid coelomycete described by Nattrass in 1933. We report five casesof N. mangiferae infections in São Paulo, Brazil. This fungus wasisolated from interdigital lesions on the feet in one patient, toenails in threecases and fingernails in the other one. The infections were initially consideredto be caused by a dermatophyte. Although there are only a few cases describedin the medical literature, the five cases reported suggest that N. mangiferaeshould be taken into consideration in the differential diagnosis of tinea pedisinfections. 相似文献

Fusarium species are common soil saprophytes and plant pathogens that have been frequently reported as etiologic agents of opportunistic infections in humans. We report eight cases of onychomycosis caused by Fusarium solani (4) and Fusarium oxysporum (4) in São Paulo, Brazil. These species were isolated from toenails in all cases. The infections were initially considered to be caused by dermatophytes. The clinical appearance of the affected toenails was leukonychia or distal subungual hyperkeratosis with yellowish brown coloration. The eight cases reported here suggest that Fusarium spp. should be taken into consideration in the differential diagnosis of tinea unguium. 相似文献

Eumycetoma is a mycotic disease caused by saprophytic soil fungi that are usually inoculated through minor injuries. A case
of mycetoma in a Brazilian farmer aged71 years is reported. This patient presented erythema and edema on the dorsal surface
of the left hand with multiple crusted and cicatricial lesions. No macroscopic grains were observed. The histopathological
findings showed grains consisted of numerous hyphae which stained well with Gomori-Grocott method. This material obtained
by cutaneous biopsy was submitted to culture on Sabouraud’s medium and the colonies were identified as Fusarium solani. The radiological studies revealed bone osteolytic lesions and the ultrasound showed pseudocysts and fistulae at the site
of this infection. The patient was treated with oral ketoconazole with a good clinical response.

Sporotrichosis is a mycotic disease caused by cutaneous inoculation of the dimorphic fungus Sporothrix schenckii. The primary
lesion can spread and often develop a unilateral lymphocutaneous lesions or, rarely, disseminated disease. We report a lymphangitic
sporotrichosis case with ulcerated erythematous nodules distributed bilaterally on the posterior and medial aspect of the
both legs, probably due to multiple inoculations. The treatment with oral potassium iodide was satisfactory.

Onychomycosis is a fungal infection of the nails with broad aetiological scope, and it represents 18–40% of all onychopathies
and 39% of all superficial mycotic infections. From July 1996 to December 1999, samples of nails were collected from 588 patients
with presumptive diagnosis of onychomycosis at the Dermatology and Mycology Divisions EPM\UNIFESP, Brazil, and the diagnosis
was confirmed in 247 of these cases. The most common pathogens isolated in this study were yeasts in 52% of positive cultures
(Candida albicans 18.3%, Candida parapsilosis 13.8%, other species of Candida 15.4% and other yeasts 4.6%), followed by dermatophytes in 40.6% of positive cultures (the most commonly isolated organisms
were Trichophyton rubrum in 33.2%, followed by Trichophyton mentagrophytes in 6.3% and others 1.2%). Non-dermatophyte moulds were isolated in 7.4% of positive cultures (Fusarium spp. 4.5%, Nattrassia mangiferae 2.3% and Aspergillus spp. 0.6%). Distal and lateral subungual onychomycosis (DLSO) was the commonest clinical pattern 44.6% followed by free edge
onycholysis (FEO) 38.8% and others. In conclusion, this study demonstrated that T. rubrum is the main agent causing onychomycosis in toenails, and species of genus Candida were the main agents isolated in fingernail onychomycosis in our region. 相似文献
