“…Framil et al reported a predominance of M. sympodialis in patients who had experienced more relapses; nevertheless, this finding was not confirmed in the present study. 8 The most prevalent sites of infection were the back, chest and abdomen in the case of most of the species and this finding is in agreement with the results published by Miranda et al (2006), who also reported the back and chest as being the most common sites of the lesions. 9 No statistically significant difference was found between the species as a function of gender, age or the duration of the lesions.…”

Pityriasis versicolor (PV) is a disease with worldwide distribution. Twelve different species of Malassezia yeast have been described. The objective of this study was to determine which species of Malassezia are more prevalent in patients with pityriasis versicolor. Samples were collected by scraping the lesions of 87 patients with a clinical suspicion of pityriasis versicolor. The samples were then submitted to fungal microscopy and culture to identify the species. The species found were: Malassezia sympodialis (30%), Malassezia furfur (25.7%), Malassezia globosa (22.7%), Malassezia restricta (12.1%), Malassezia obtusa (7.6%) and Malassezia slooffiae (1.5%). Keywords: Dermatology; Dermatomycoses; Fungi; Mycoses. Resumo:A pitiríase versicolor é uma doença de distribuição universal. Existe a descrição de 12 espé-cies de malassezia. O objetivo deste estudo foi determinar quais as espécies de malassezia mais prevalentes nos pacientes com pitiríase versicolor. Foram realizadas as coletas através de raspado das lesões nos pacientes com suspeita clínica de pitiríase versicolor e posterior exame micológico e cultural para identificação final da espécie. Foram coletadas amostras de 87 pacientes. Quanto às culturas, 30% foram de Malassezia sympodialis, 25,7% de Malassezia furfur, 22,7% de Malassezia globosa, 12,1% de Malassezia retrita, 7,6% de Malassezia obtusa e 1,5% de Malassezia sloofiae.

“…[2] A few studies have found M. sympodialis to be the most common species; [5,7] we found it to be second most frequent, as in other studies also. [3,[8][9][10][11] M. furfur is also responsible for pityriasis versicolor, particularly under tropical climate. [12] In the present study, this species was isolated in 6.9% of patients, quite similar to another report (7.8%).…”

“…Pityriasis versicolor is a chronic superficial fungal disease usually located on the upper trunk, neck or the upper arms [12,13], the back and chest being the most common sites of lesions [14]. Currently, therapeutic interest is focused on synthetic ‘-azole’ antifungal drugs, which interfere with the sterol metabolism of the fungi [15,16,17,18].…”

Background: Ketoconazole is a typical treatment available for pityriasis versicolor; tretinoin cream is effective, too. Adapalene gel is a tretinoin derivative and has a lower incidence of irritation compared with other topical retinoid products. However, there are no reports on adapalene gel for the treatment of pityriasis versicolor. Objective: To study the effect of adapalene gel comparing the treatment with adapalene gel and 2% ketoconazole cream in pityriasis versicolor. Methods: Eighty patients suffering from pityriasis versicolor were randomly divided into two groups; one group were treated with 2% ketoconazole cream topically twice daily for 2 weeks, adapalene gel was used for the other group in a similar fashion. Results: There were no significant differences in efficacy between the two groups. No major side effects were noted in any of the groups either. Conclusion: Adapalene was the favorable option in the treatment of pityriasis versicolor. The probable therapeutic mechanism of adapalene is also discussed.
