BACKGROUND Pytiriasis versicolor is an infectious disease caused by several Malassezia species which has a tendency to become relapsing or chronic. OBJECTIVES This study was conducted in an attempt to investigate the clinical course of pityriasis versicolor with regard to the number of relapses after a 12-month therapy and correlate this number with isolates of Malassezia species. MATERIAL ...

Pityriasis versicolor is a common superficial fungal infection of the skin which is caused by various species of yeast of the genus Malassezia and is clinically characterized by scaly hypo pigmented or hyper pigmented macules usually involving the upper trunk, upper arms, neck and abdomen [1]. Lesions of pityriasis versicolor confined to face has rarely been reported. In this article the author...

Epidermodysplasia verruciformis is an inherited disorder, characterized by multiple plane warts, pityriasis versicolor-like lesions, defects of cell-mediated immunity, and tendency to develop skin malignancies, primarily on sun-exposed areas. In this article, we present a case of epidermodysplasia verruciformis with multiple plane warts, pityriasis versicolor-like lesions, and squamous cell car...

Pityriasis versicolor is a superficial fungal infection of the skin caused by yeast of the genus Malassezia. It is characterized by hypopigmented or hyperpigmented macules and patches usually involving the trunk [1]. The variants of pityriasis versicolor include hypochromic, hyperchromic, combination of hypo-hyperchromic, erythematous, circinate, atrophic and acral [2-4]. However, the follicula...

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...

conclusions this study showed m. globosa to be the most common malassezia species isolated from malassezia skin disorders in kashan, iran. the pcr-rflp method was useful in the rapid identification of the malassezia species. by using these methods, the detection and identification of individual malassezia species from clinical samples was substantially easier. patients and methods a total of 14...

BACKGROUND Pityriasis versicolor is a common chronic superficial fungal infection of the skin. OBJECTIVE The purpose of this study is to determine the frequency of visits for pityriasis versicolor and to assess how it is currently being treated. METHODS Data from the National Ambulatory Medical Care survey were used from the years 1990-1999. RESULTS There were 2.9 million visits per year ...

OBJECTIVE To determine the efficacy of topical or systemic agents in the treatment and prevention of pityriasis versicolor. DESIGN Systematic review and meta-analysis. DATA SOURCES The Cochrane Skin Group Specialized Register (to June 2008), Cochrane Central Register of Controlled Trials, MEDLINE (1950 to June 2008), EMBASE (1974 to June 2008), LILACS (to March 2009), the gray literature, a...

BACKGROUND Skin pigmentary changes of pityriasis versicolor may occur as either hyperpigmented or hypopigmented lesions, depending on the outcome of interactions between Malassezia yeasts and the skin, such as lipoperoxidation process, stimulus of inflammatory cell to melanocytes, and increased thickness of keratin layer. OBJECTIVE To investigate skin characteristic factors that enhance the s...

BACKGROUND Malassezia species are lipophilic yeasts found on the skin surface of humans and other warm-blooded vertebrates. It is associated with various human diseases, especially pityriasis versicolor, which is a chronic superficial skin disorder. OBJECTIVES The aim of the present study was to identify Malassezia species isolated from patients' samples affected by pityriasis versicolor, usi...
