What should I do if I have the skin disease pityriasis rosea?

Skin diseases have always been a type of disease with a very high incidence in life. There are many types of skin diseases, but they all have one thing in common, that is, they all affect physical health by infecting the surface skin. Therefore, the key to preventing skin diseases is to protect the skin's hygiene from being destroyed. Among skin diseases, pityriasis rosea is relatively rare, but the harm of this disease is very serious. It will form clusters of fiery red rose-shaped rashes on the patient's body, making the patient feel itchy. Let's take a look at what to do if you have the skin disease pityriasis rosea.

Pityriasis rosea is a common inflammatory skin disease that occurs on the trunk and proximal limbs. It is characterized by rose-colored macules of varying sizes and numbers, covered with sugary scales. The disease is self-limiting and usually lasts for 6 to 8 weeks before healing on its own. However, there are also cases where the disease does not heal for a long time, because many patients with pityriasis rosea are prone to residual pigmentation after delayed treatment. Should be treated early.

Histopathology: It manifests as nonspecific chronic inflammatory changes, with focal parakeratosis, mild acanthosis, spongiosis and intracellular edema in the epidermis, and moderate vascular dilation, edema and lymphocytic infiltration in the superficial dermis.

Because the disease is self-limited, the goal of treatment is to relieve symptoms and shorten the course of the disease.

1. General treatment

During the acute phase, washing with hot water and washing with soap are contraindicated. Do not use strongly irritating external medications. Clinically, many patients have their condition aggravated, prolonged, or transformed into autosensitive dermatitis due to improper local care.

2. Antihistamines

Antihistamines such as chlorpheniramine, cyproheptadine, terfenadine and chlorpheniramine can be used appropriately, and vitamin C can also be used.

3. Traditional Chinese Medicine

The treatment principle of traditional Chinese medicine is to clear away heat and cool blood, dispel wind and relieve itching. Generally, Liangxue Xiaofeng Decoction is effective. For mild patients, Lithospermum officinale can be used, decocted in water and taken once a day.

4. Ultraviolet radiation

After the acute inflammatory period is over, ultraviolet spot irradiation can promote the disappearance of lesions.

5. Topical medication

Calamine lotion can be applied externally.
