The macula or mother spot of the pink pityriasis  can be up to 10 centimeters in size .

After about 1-2 weeks, a diffuse rash occurs, with minor cutaneous lesions (daughter spots) that:

  • They originate from the center of the body,
  • They scatter with a pine-like shape that seems to fall.


Types of pyrrhose osseous

1. Pityriasis giantus: manifests in the mouth, nails, genitals and scalp, but has the characteristics of classical disease;

2. Pityriasis ryneus circinate and marginalized of Vidal : it is characterized by red spots of larger dimensions, but they are far from each other and are less numerous. This can last for several months.

3. Rosy pityriasis vesicularis: mainly affects young blacks.

4. Urticate pityriasis rosea: occurs together with urticaria.


Causes of the throat fever of Gibert

Doctors do not know what causes pityriasis rosea.
Some believe it is infectious and caused by herpes virus type 6 and 7, but scientists must still prove this theory.
People between the ages of 10 and 40 and pregnant women are more likely to get pityriasis rosea, but it can happen:

  • At any age,
  • To people of any race.

It is more frequent:

  • In the spring,
  • In the fall.


Symptoms of pink pityriasis

The symptoms of pityriasis rosea can progress in three distinct phases. However, there is an atypical form of the disease in which the first or second phase described below is lacking.


Early Symptoms

Some people with pityriasis rosea have some initial symptoms of a few days to a week before the appearance of the rash.
These include:
1. Fever (rare)
2. Nausea
3. Loss of appetite
4. Headache
5. Joint pain  (rare)
6. Sore throat
7. Feeling of general malaise
8. Swollen lymph nodes (rare )
These symptoms usually disappear over time and the individual moves on to the stage of skin eruption.


Second stage: the great macule

Generally, the successive phase is the appearance of a red and oval patch of scaly skin that grows for a few days.

The edge of the stain is

  • Defined,
  • A little scaly.

In the center of the skin:

  • There is a fine peeling,
  • The color is similar to the rest of the skin.

This eruption is called Gibert’s mother spot or medallion.
The macula has a size ranging from 2 to 10 cm.
The spot usually appears:

  • In the trunk (abdomen, thorax, back)
  • In the neck.

Rarely the macula of the husk of Gibert appears:

  • In the face,
  • In the scalp,
  • In the genital area.


Third stage: secondary rash

Generally, a secondary skin rash:

  • It develops within a few days after the appearance of the round spot,
  • It can continue to spread in the next two to six weeks.

The rash consists of small raised spots that are usually between 1 cm and 2 cm in size .
Most people develop several blemishes:

  • No trunk
  • In the neck,
  • In the arms,
  • In the upper thighs.

Usually the face is not affected.

In people with:

  • Clear skin , the papules are reddish-pink,
  • Dark skin , the rash of the skin can be gray, brown or black.

Generally, the papules form a symmetrical figure:

  • It looks like a Christmas tree in the upper back, and in fact the spots are obliqued like the branches of the tree.
  • With a “V” shape on the chest.

The secondary rash is not painful, but it can cause itchy skin .
The itching can be moderate to severe.
It often worsens:


Could pityriasis rosea be caused by a viral infection?

According to the most recent scientific studies, the origin of pityriasis could be a viral infection .
The virus was recently identified in the herpes virus family.
Children and young people are most affected by unknown reasons.
Pityriasis rosea does not appear to be contagious, but other family members should practice more rigorous personal hygiene to feel more relaxed.


Diagnosis of pyrrhose osseous

The doctor diagnoses the pityriasis rosea examining the rash.
The diagnosis can be difficult when one sees only the large macule because the disease is often confused with ringworm or eczema at this stage.
In the differential diagnosis, the doctor should also rule out:

After the appearance of the rash, the diagnosis is simple.
skin biopsy is performed only in case of persistent pityriasis rosea, that is, if no more.


Treatment of the throat rush of Gibert

Since pityriasis rosea usually passes between two and twelve weeks after onset, treatment is not necessary if a severe itching does not occur.

There are three main treatments:

  • Emollients – Skin creams that are designed to moisturize the skin
  • Cortisone topical – creams or ointments containing cortisone
  • Antihistamines – a type of medicine widely used to treat allergy symptoms such  as itching.

If that does not work, the patient may be referred to a dermatologist (specialist in the treatment of skin diseases) who may recommend a treatment called phototherapy with ultraviolet UVB rays.

The emollients are creams, ointments and lotions designed to help skin stay hydrated and relieve itching.
It is possible to use the emollient properties when the itching occurs.
Apply the cream gently, we should avoid rubbing the skin vigorously.
Some emollients:

  • They are designed to act as a soap replacement product,
  • They are usually recommended because normal soap can irritate the rash.

These types of emollients are available as over-the-counter medications.

Topical cortisone
We recommend talking to your doctor if emollient products can not reduce the itching.
More therapies may be needed with a topical cortisone.
Cortisone in ointment or cream that is applied directly on the skin can be of two types:

1. O creme hydrocortisone,
2. A betamethasone.

The main purpose of topical cortisone is:

It is generally recommended to apply the cream or ointment with cortisone on the affected areas of the skin once or twice a day.
If you apply cortisone as directed by your doctor, the side effects of cortisone will be rare.
Some people may feel a slight burning sensation in the skin, or the sensation of a sting during the first time they spread the cream.
This side effect is temporary and passes after the body becomes accustomed to the medication.


In case of difficulty sleeping because of itching, your doctor may prescribe an antihistamine such as:

  • Hydroxysin (Hixizine),
  • Corfenamine (Dexchlorpheniramine).

Sedative antihistamines are medications indicated for the treatment of allergies, such as allergic rhinitis, but among the side effects they cause drowsiness for many patients.

  • It is usually necessary to take this medicine before bed.
  • Many people feel very sleepy when they wake up the next morning.
    In this case, avoid driving machines.


Treatment of pink pityriasis with UVB rays

If the symptoms do not respond to the treatments indicated above, your doctor may recommend phototherapy with ultraviolet UVB rays.
This treatment involves controlled exposure of the skin to ultraviolet light for a few seconds to several minutes at regular intervals under the guidance of a specialist.
It is not the same as a tanning solarium.
However, there are some doubts about the efficacy of UVB treatment for pityriasis rosea.

  • Some medical studies show that it can relieve itching,
  • Others have noted that it only helps to improve the appearance of the rash during the first few weeks of the illness.

According to some doctors treatment with UVB rays could cause skin blemishes even after recovery.
Some people believe that exposing the skin to natural sunlight for short periods can be helpful.
Care should be taken not to spend too much time in the sun because prolonged exposure may:

  • Damage the skin,
  • Increase the risk of developing melanoma .


Other treatments and medications for pityriasis rosea

Different treatments and medications have been proposed for pityriasis rosea, but there are doubts about efficacy.
These include:

  • Acyclovir is an antiviral drug designed to treat herpes infections
  • Erythromycin is a type of antibiotic used to treat bacterial infections
  • Oral cortisone (tablets)

It is necessary to be aware that there is little scientific evidence demonstrating the efficacy and safety of these drugs for pityriasis rosea.

Natural remedies for pityriasis rosea

These steps may help alleviate the discomfort caused by pityriasis rosea:

1. Wash in warm water.
2. Take a bath in a tub with oatmeal or baking soda .
Oatmeal can be found in the pharmacy.
3. Spread a calamine cream on the rash.
4. Apply an aloe vera gel over the stains.
5. Rub a zinc oxide paste or cream to reduce the size of the spots and itchiness.
6. Follow a healthy diet without red meat, fried foods, coffee and dairy products.


How long does pityriasis rosea? Can you return?

The rash of the skin is not contagious.

In most cases, the healing time of the large macula and the secondary eruption is about twelve weeks, although some symptoms persist for up to six months.
When the rash goes away you may notice some light or dark areas on the skin.
These should return to normal within a few months.
Pityriasis rosea does not cause scars .

Generally, when the pink pityriasis disappears it leaves no white spots or other bands.
Relapses are rare, a person with this disease has only a two percent chance of recurrence.
