Rose lichen , or pink lichen Gibber ( lat. Pityriasis rosea ), is an infectious-allergic skin disease characterized by spotted rashes. The average time of the course of the disease is from 4 to 6 weeks [3] , in rare cases - up to six months. It is believed that this infection is contagious, but this judgment is erroneous. People get sick with pink deprivation mainly from 10 to 35 years old; the development of the disease is favored by colds and a decrease in immunity [4] .

The course of the disease
Lichen pink is a skin disease from the group of infectious erythema.
Etiology, pathogenesis
The causative agent of pink lichen is not exactly known (there is an assumption that this could be any damage to the outer skin of the skin). There is an opinion that pink lichen is caused by herpesvirus type 7 and, less commonly, type 6 , as evidenced by the facts of their identification in active form during the early stage of the disease [5] . The most common opinion is that the disease often appears after a cold infection. Outbreaks of the disease are observed in people of both sexes aged 10 to 55 years, most often in spring and autumn, at a time when immunity is weakened. Cyclic and relapse-free are characteristic, apparently due to the development of immunity.
Clinical picture
The disease begins (usually in the background or shortly after a cold) with the appearance on the skin of the body of a single pink papule with a diameter of 2 cm or more (the so-called maternal plaque), the central part of which gradually acquires a yellowish tinge, as if wrinkled and begins to peel off slightly. Usually, a few days after the appearance of maternal plaque on the skin of the trunk and limbs, multiple small oval pink spots with a diameter of 0.5-1 cm appear along the Langer lines . Gradually in the center of the spots barely noticeable dry folded scales are revealed, and on the periphery - the edge of the border, free from scales, is revealed.
Treatment
The disease usually goes away on its own. During the onset of secondary rashes, friction and pressure of the elements are not recommended to avoid the appearance of an irritated form of pink lichen. For treatment, zinc liniment is used, applying it to the skin (on the entire surface of the body) 2 times a day. In the first week you can not swim, as this leads to the spread of lichen throughout the surface of the body. Apply UFO for 10-15 seconds, five to seven procedures.
With severe itching, antihistamines, locally low-strength corticosteroids (hydrocortisone) and prescription antipruritic mixtures are prescribed. Also take vitamin C. The duration of treatment is three weeks.
