Lichen rosea (Giber’s disease) is an inflammatory skin disease, presumably of a viral nature.
The causative agent of the disease is not exactly known. However, pink lichen usually appears after hypothermia, after colds or other diseases. The peak incidence of pink lichen occurs in the autumn-spring period. Young people get sick more often. Pityriasis rosea is a slightly contagious disease, rare cases of familial morbidity are described.
Manifestations of rosacea
A round-shaped “maternal” plaque appears on the skin of the trunk with clear borders of pink or yellow-brown. The plaque is small – 1.5-2 cm in diameter. The central part of the plaque is wrinkled in the form of tissue paper and begins to peel off. A bright red rim is formed, the hearth becomes like a medallion.
After 5-10 days, “daughter” foci appear, the number of which can increase for several weeks. The plaques are located along the lines of least stretching of the skin. The rash can persist for about 1.5-2 months. Itching may be present, although more often subjective sensations are not expressed.
Sometimes the first rashes are accompanied by a slight fever and general malaise.
When irritated (washing with a washcloth, rough clothes, caustic substances, soap) and susceptibility to allergic reactions eczema can form at the site of the plaques, a secondary bacterial infection will join. In these cases, recovery slows down.
A sparing diet is prescribed, mainly dairy and vegetable, alcohol, spicy and fatty foods are excluded.
In the first 2-3 weeks, you can not take a bath. You can wash under a warm shower using mild detergents, without a washcloth.
The sick person should protect the skin from exposure to sunlight until complete recovery, and also avoid hypothermia. Do not wear synthetic clothing.
If general recommendations are followed, lichen often resolves without specific treatment. But sometimes there is a need for drug treatment: antibiotics, corticosteroid ointments, antihistamines, powders are prescribed.
The prognosis of the disease is favorable. As you recover, the rash turns pale and disappears without a trace. Relapses are rare.
