503 Indian Journal of Dermatology, Venereology, and Leprology | July-August 2012 | Vol 78 | Issue 4 clinically characterized by combination of pityriasis versicolor (PV)-like hypopigmented lesions, verruca plana-like lesions and seborrhoeic keratosis-like verrucous plaques. These PV-like lesions, especially in sun exposed areas, have higher risk of developing squamous cell carcinoma (SCC). Thes...

OBJECTIVE To make a comparison between terbinafine 1% cream and ketoconazole 2% cream in the treatment of pityriasis versicolor. METHODS This randomized single blind study included 110 patients with clinical diagnosis of pityriasis versicolor and positive mycological test for Malassezia furfur. The patients were randomly assigned to two groups. Group 1 used terbinafine cream and group 2 appli...

A Review of the Diagnosis and Management of Fungal Skin and Nail Infections D’Arcy Little, MD, CCFP, Lecturer and Academic Fellow, Department of Family and Community Medicine, University of Toronto,Toronto, ON. SKIN DISORDERS Fungal Skin Infections Normally, the dryness and regular shedding of the skin’s keratin layer prevents microbial colonization.3 However, skin trauma, irritation or macerat...

Pityriasis versicolor (PV) is a common clinical problem associated with Malassezia species (Malassezia spp.). Controversies remain regarding the specific species involved in the development of PV. This study analyzed the difference in Malassezia spp. distribution in lesional and nonlesional skin in Chinese PV patients. A paired design was applied. Lesional and nonlesional scales from 24 cases w...

The present study is designed to evaluate the application of a simple method for rapid identification of Malassezia furfur among other Malassezia spp. based on production of a brownish-red pigment and its diffusion into the medium containing L-tryptophan as a sigle source of nitrogen. 91 strains of Malassezia (20% M. furfur, 2% M. sympodialis, 5% M. obtosa and 73% M. globosa) isolated from skin...

Malassezia spp. form part of the normal human cutaneous flora and are implicated in several mild, but recurrent cutaneous diseases, such as pityriasis versicolor, Malassezia folliculitis, seborrhoeic dermatitis, and, with lesser frequency, a range of other dermatological disorders. Malassezia spp. have also been associated with cutaneous and systemic diseases in immunocompromised patients inclu...

BACKGROUND Pityriasis versicolor (PV) is a cutaneous pigmentation disorder caused by a lipophilic yeast of the genus Malassezia sp. It is a superficial mycosis characterized by well-defined, slightly scaly skin lesions of variable color. In Brazil, the number of reported cases is small, and there are few epidemiological studies. OBJECTIVES to assess incidence, characteristics of the lesions, ...

Although pityriasis versicolor is the only human disease for which Malassezia yeasts have been fully established as pathogens, it is still not clear which species are implicated. Most studies carried out in recent years support our hypothesis —proposed in 1999— that Malassezia globosa is the predominant species in pityriasis versicolor lesions, at least in temperate climates. Confirmation of th...

Having enjoyed considerable opportunities of seeing several varieties of the affections of the skin known by the name of Molluscum contagiosum or psoriasis, prurigo, pityriasis versicolor, scabies, eczema, &cM and having resorted to all modes of available treatment for these troublesome and inveterate diseases, I may briefly record the result of my own experience in tlio management and eradicat...

The authors report a case of pityriasis versicolor circinata whose isolated etiologic agent was Malassezia sympodialis in a 34-year-old woman. The isolation and identification of Malassezia sympodialis were accomplished with modified Dixon's agar, and the molecular method used to confirm the species was polymerase chain reaction and restriction fragment length polymorphism analysis (PCR-RFLP).
