Pink lichen

Pink deer is a skin disease from the group of infectious erythema.

Etiology, pathogenesis. The causative agent of pink lichen is unknown (a virus is assumed). The development of the disease contributes to the common cold. Outbreaks are noted more often in the spring and autumn. Characterized by the cyclical and disease-free, apparently due to the development of immunity.

Clinical picture. The disease begins (usually on the background or soon after a cold disease) from the appearance on the skin of the trunk of a single large rounded spot of pink color 2 cm in diameter or larger (the so-called mother plaque), the central part of which gradually acquires a yellowish tint, as it wrinkles and begins to slightly peel . Usually, a few days after the appearance of the maternal plaque on the skin of the trunk and limbs, multiple small oval pink spots with a diameter of 0.5-1 cm, located along the Langer lines, appear. Gradually, barely noticeable dry folded scales appear in the center of the spots, and on the periphery there is a red border, free from scales, which makes the spots look like medallions. The rash is not prone to fusion. Subjective sensations are often absent, but itching is possible. The duration of the disease is 4-6 weeks, after which the spills disappear spontaneously. With irrational irritating therapy, frequent washing, as well as with excessive sweating and in individuals with allergic reactions, rashes can be classified and remain for a much longer period of time.

The diagnosis is based on a characteristic clinical picture. Syphilitic roseola is excluded on the basis of the presence of peeling, maternal plaque, negative serological reactions and the absence of other signs of syphilis.

Treatment. Prohibit washing and wearing of woolen and synthetic underwear. Assign calcium preparations, antihistamines, ascorutin. In the case of common forms of the disease with a pronounced temperature response, antibiotics of a wide spectrum of action (olethrin can be additionally prescribed 0.25 g 4 times a day). Outwardly: powdering with an aqueous stirring suspension (zinc oxide, starch, talc 10 g, glycerin-20 ml, distilled water - 100 ml), corticosteroid ointments.
