Onychomycosis caused by Arthrinium arundinis in leprosy patient : case report

We report a case of a 56-year-old Brazilian woman, with relapsing lepromatous leprosy, and onychomycosis caused by a non-dermatophyte filamentous fungi. The pathogenic fungi was identified as Arthrinium arundinis and treated with chemical abrasion of the nail with 40% urea and application of terbinafine cream. Onychomycosis caused by Arthrinium species is rare, and this is the second reported case

Clinical-epidemiological characteristics of Sporotrichosis cases in Rio Grande do Sul, Brazil: a 16-year study

Background: Sporotrichosis is a subcutaneous fungal infection that occurs worldwide, although its highest incidence is in tropical and subtropical areas. In Brazil, it is an hyperendemic disease that affects animals and humans. Objective: To report cases of sporotrichosis in a dermatology referral service, in the state of Rio Grande do Sul. Methods: Retrospective, observational, descriptive study, from 2003 to 2019. Data were selected from patients who had skin lesions suggestive of sporotrichosis, and who had positive direct and/or cultural mycological examinations of Sporothrix spp.. Clinical records were reviewed in charts. Results: 61 cases of sporotrichosis were identified, with an annual average of 4 cases. There was a predominance of males (54.1%; n=33) and white skin color (77.0%; n=47). The mean age was 45.9 years (standard deviation = 21.2), with the predominant age group between 25 and 60 years (41.0%; n=25). The sample consisted mainly of patients residing in the interior of the state of Rio Grande do Sul (47.5%; n=29). Conclusions: This study contributes with updates on the epidemiological situation of sporotrichosis in the state of Rio Grande do Sul

SIXTEEN YEARS OF DERMATOMYCOSIS CAUSED BY Candida spp. IN THE METROPOLITAN AREA OF PORTO ALEGRE, SOUTHERN BRAZIL

The yeasts of the genus Candida infect skin, nails, and mucous membranes of the gastrointestinal and the genitourinary tract. The aim of this study was to determine the prevalence of dermatomycoses caused by Candida spp., and their etiological aspects in the metropolitan area of Porto Alegre, Brazil. A retrospective study with data obtained from tertiary hospital patients, from 1996 to 2011, was performed. The analyzed parameters were date, age, gender, ethnicity, anatomical region of lesions, and the direct examination results. For all the statistical analyses, a = 0.05 was considered. Among positive results in the direct mycological examination, 12.5% of the total of 4,815 cases were positive for Candida spp. The angular coefficient (B) was -0.7%/ year, showing a decrease over the years. The genus Candida was more prevalent in women (15.9% of women versus 5.84% of men), and in addition, women were older than men (54 versus 47 years old, respectively). There was no difference between ethnic groups. The nails were more affected than the skin, with 80.37% of the infections in the nails (72.9% in fingernails and 7.47% in toenails). Our study corroborates the literature regarding the preference for gender, age, and place of injury. Moreover, we found a decrease in infection over the studied period

Cutaneous phaeohyphomycosis caused by Exophiala xenobiotica : a case report

We report a case of phaeohyphomycosis that affected the leg of a 45-year-old Brazilian man, car mechanic and renal transplanted. The direct mycological examination evidenced dematiaceous septated hyphae. The pathogenic fungal species was identified as Exophiala xenobiotica. Antifungal activity in vitro revealed terbinafine as the best antifungal. For treatment, it was chosen surgical excision of the entire lesion and used systemic itraconazole. Phaeohyphomycosis caused by Exophiala xenobiotica is extremely rare and is closely related to transplant patients
