Rosea Skin

Pityriasis Rosea is a common skin disease characterized by a rash that can last from several weeks to several months. In most cases, the condition begins with one single, scaly, oval patch (or "Herald Patch") on the chest or back and is followed a week or two later, with more pink spots on chest, arms, legs and back. The face is usually not affected, however.

The first "Herald patch ranges between 2 cm and 10 cm, while the surfaces are later, between 1 cm and 2 cm. Patches on the back are often a pattern that resembles the silhouette of a tree (or "Christmas tree"). Herald patch is sometimes confused with other conditions such as ringworm, psoriasis and eczema. Before the advent of the "Herald" patch, you may experience symptoms such as fatigue, nausea, sore throat, headache.

The exact cause of pityriasis rosea is unknown but is believed to be caused by a virus. The disease is not contagious and most commonly affects adolescents and young adults aged 10 and 35. Although pityriasis rosea may be acquired at any time of year, it is more often seen in spring and autumn. Dermatologists diagnose this condition by inspecting the rash, but may also conduct blood tests and skin biopsies by examining skin samples from the affected area under a microscope. tests of potassium hydroxide may also be performed to rule out fungal infections.

Treatment

For mild cases, no treatment may be necessary and the disease may disappear by itself between 6 and 12 weeks. Typically, patients are encouraged to take a bath or shower with clean water, bath oils, lubricants and light creams and soap substitutes other than soap can worsen the rash. Itching can be treated with steroid creams and ointments or taking antihistamines. More severe cases can be treated with ultraviolet light treatments (phototherapy).
