Tinea versicolor is a chronic fungal infection that affects the top layer of human skin. It can be recognized by scaly patches that change color over time from yellowish to brownish and even coffee-colored. Treatment of this disease, as a rule, is quite long, so you need to see a doctor when you find the first signs of lichen.
Causes of multi-colored lichen
Pityriasis versicolor, also called pityriasis, appears as a result of the growth of fungi of the genus Pityrosporum orbiculare and Malassezia furfur, located in the stratum corneum at the mouth of the follicles. Under the microscope, they resemble clusters of curved, thick filaments.
Tinea versicolor is not a contagious disease, as the fungi that provoke it are present on the skin of most adults.
The reasons for the growth of these fungi have not yet been fully understood, however, doctors believe that the appearance of pink lichen is directly related to a weakened immune system, an individual predisposition to such a disease, increased sweating and a special chemical composition of sweat. The cause of pathogenesis can also be a violation of physiological processes in the stratum corneum of the epidermis.
It was observed that lichen rosacea more often affects young men and women than children, as well as those whose bodies are weakened by tuberculosis, vegetative neurosis with excessive sweating or diabetes mellitus.
Symptoms of multicolored lichen
Like other skin conditions, tinea versicolor can be identified by a number of signs. The most common of these, which can be seen with the naked eye, are yellowish or light brown spots on the skin, originating from hair follicles and spreading over the upper torso. As a rule, the localization of spots is the chest, back, neck, shoulders and lateral surfaces of the trunk. Although it is rare in children and adolescents, tinea versicolor is much more common in children and adolescents - it can include the armpits, abdomen, arms, legs, and scalp.
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 lichen began to be called color. On the other hand, in severely tanned people, spots, on the contrary, can become lighter in relation to the basic skin tone. Many spots merge together, forming intricate patterns similar to a geographic map.
Only a doctor can correctly diagnose this disease based on studies of skin scrapings. After that, as a rule, a course of treatment is prescribed with special antifungal pills, sprays or sulfur-salicylic ointment. The patient may also be prescribed sunbathing to help fade the spots. It usually takes a long time to treat versicolor versicolor, sometimes more than one month. Relapses occur quite often.
