    The causative agent of multi-colored lichen was described by G. Robin in 1853, and in 1951 M. Gordon singled round and oval forms of the pathogen in places eruptions multi-colored lichen, and within healthy skin, attributing it to the yeast-like fungi, and its rounded version of the proposed name Pityrosporum orbiculare.

    What contributes to the development of zoster

    chromophytosisPityriasis versicolor - a diseasespread everywhere, but most often it occurs in countries where elevated temperature and humidity. Ill persons of young age, disease registers and children.

    The risk of multi-colored lichen growspeople who suffer from excessive sweating, a specific chemical composition of sweat, favorable for the pathogen of skin pH, with concomitant diseases: endocrine disorders, chronic diseases of the gastrointestinal tract, and immune deficiency.

    In recent years, a clinically establishedgenetic predisposition to the development of multi-colored lichen. Often the disease develops in the presence of pulmonary tuberculosis, Hodgkin's disease, as these diseases are often accompanied by increased sweating.
    Transmission of the pathogen from the patient's multi-coloredringworm or carrier, for example, a total bed, or through shared with them clothes or underwear, in principle, possible. However, most people are carriers of the same fungi that are on the skin (in areas rich in sebaceous glands) and do not cause disease.

Eruptions due to loosened horny layer stain intensity as compared with the surrounding healthy skin. Just do not try to put this test yourself as to diagnose the disease can only be a doctor.

    In the study using a Wood's lamp in defeat marked yellow glow.

    Microscopically in scales taken from lesions pityriasis versicolor and treated with a solution of 15-20% caustic (KOH), defined budding fungus cells and pseudomycelium.

    Another method of diagnosis - use of the environmentSaburo, which is formed after 3 weeks creamy white culture (cell colony growth on the environment), which has similarities with the yeast. Microscopic examination revealed budding cells of the fungus.

    Ointments "kill" the fungus

    If you choose among the many antifungaldrugs, widely represented in the modern Russian market, preference should be given to those who, at first, can accumulate in those layers of the skin, which develops fungal process, and secondly, do not penetrate into those layers, where the vital activity of fungi impossible.
