    Abstract:
    Pityriasis versicolor (Tinea versicolor) is a superficial chronic fungal infection caused by Pityrisporum species which are normal "inhabitants" of the cutaneous flora. The morphologic changes from yeast to mycelial hypha form are important in the development of clinical lesions. The onset and course of the disease are under the influence of genetic factors, age, sex, climate, local environmental factors, malnutrition, pregnancy, oral contraceptives, corticosteroid and immunosuppressive treatment. They favorize transformation of saphrophytic to pathogenic form, and are the cause of recurrences and chronicity of the disease. The ultrastructural and immunologic studies which are carried out today would significantly contribute to a better understanding of pathogenesis of the disease. The disease is limited to seborrheic areas of the skin and commonly has three clinical forms: papulosquamous, follicular and inverse. This can make great problems in differential diagnosis. In the treatment of these patients it should be kept in mind that Pityriasis versicolor is not a primary contagious disease and that conversion of Pityrisporum depends on the predisposing factors. Numerous medicaments with local and systemic effect which are used nowaday in the treatment and prevention of pityriasis are reported. Way of application, doses, duration of therapy, advantages and disadvantages are given in detail.
