The causes and symptoms of multi-colored lichen
Causes of multi-colored lichen
The versicolor versicolor, also called the scaly, appears as a result of the growth of fungi of the genus Pityrosporum orbiculare and Malassezia furfur, located in the horny layer of the skin at the mouth of the follicles. Under a microscope, they resemble bunches consisting of curved thick filaments.The versicolor versicolor is not a contagious disease, as the fungi that provoke it are present on the skin in most adults.
The reasons for the growth of these fungi are not yet fully understood, but doctors believe that the appearance of pink lichen is directly related to the weakening of immunity, individual susceptibility to such a disease, increased sweating and a special chemical composition of sweat. The cause of the pathogenesis can also be a violation of the physiological processes in the stratum corneum of the epidermis.It has been observed that lichen versicolor often affects young men and women than children, as well as those whose body is weakened by tuberculosis, vegetative neurosis with excessive sweating or diabetes.
Symptoms of multi-colored lichen
Like other skin diseases, pityriasis versicolor can be identified by a number of signs. The most common of these, which can be seen with the naked eye, is yellowish or light brown spots on the skin, originating from hair follicles and spreading through the upper part of the body. Typically, the localization of spots is the chest, back, neck, shoulders and side surfaces of the body. Although children and adolescents have versicolor versicolor rarely, their area of spread is much wider - it may include the armpits, abdomen, arms, legs, and the hairy region of the head.
Such spots do not rise above the skin and do not cause discomfort, but over time they begin to peel off and change their color to brown or dark brown. It is for this reason that the lichen began to be called color. And in strongly tanned people, the spots, on the contrary, can become lighter in relation to the basic skin tone. Many spots merge into one, forming intricate patterns, similar to a geographical map.
Correctly diagnose this disease can only be a doctor on the basis of studies of skin scraping.After that, as a rule, a course of treatment is prescribed with special antifungal tablets, sprays or sulfur-salicylic ointment. The patient can also be given sunbathing to help the spots disappear. It is usually long, sometimes not one month to treat a multi-colored versicolor. Quite often relapses occur.
