Pityriasis Versicolor

Symptoms and Diagnosis of Pityriasis Versicolor

Those suffering from Pityriasis Versicolor may have a hard time knowing what to do about the condition. However, there are some simple steps that can help alleviate the discomfort. These steps include knowing the symptoms of Pityriasis Versicolor, the diagnosis of the disease, and the treatments available for this condition.


Symptoms of Pityriasis Versicolor include discolored patches and spots on the skin. They can appear on any part of the body, but usually, they occur on the neck, chest, and back. It is a fungus infection that is caused by a type of fungus called Malassezia. Luckily, the condition is not dangerous, but it can be bothersome. It may cause itching, and sometimes it can recur. To treat it, you can use topical medications, such as creams or tablets. However, it is recommended that you see a doctor to diagnose the problem.

The underlying causes of Pityriasis Versicolor are unclear, but there are some known risk factors. These include people who live in warm, humid environments and people who sweat a lot. These people are also more likely to have a weakened immune system. They may also have other skin conditions, such as rosacea. If you are unsure whether you have Pityriasis Versicolor, you can take a skin biopsy. If the results are positive, your doctor will decide on the best treatment for you.

The first step to treating pityriasis is to see a GP, who can prescribe a topical medication. These medicines are used to kill the fungus that causes pityriasis. They should be applied to the affected area at least once a day for several weeks. Some people experience side effects, such as stomach pain, when they take antifungal tablets. Other people may get rashes while taking these drugs.

Another way to treat pityriasis is with systemic therapies. These medicines are used to treat the fungus over a longer period of time, so they can help you to better comply with the medication. These medicines, including fluconazole and ketoconazole, can be taken once or twice a week for a few weeks. They can also be used to prevent a recurrence of the disease.

To prevent a recurrence of pityriasis, you should limit the amount of sun you receive. Wearing sunscreen and wearing a hat can help protect your skin from the sun’s rays. It is also important to avoid activities that make you sweat a lot. This includes playing sports, being in a crowded room, or being exposed to a high degree of heat.

Alternatively, you can try an antifungal shampoo, which can be effective in killing the fungus that causes pityriasis. You will need to lather the shampoo on the affected areas of the skin for about five to ten minutes. You should dilute the shampoo with water before applying it. Some shampoos can be harsh and can burn the skin, so be careful.

For the most part, the symptoms of pityriasis will go away on their own. They will usually fade within eight to 12 weeks. If the rash continues to reappear after treatment, it is a good idea to see a doctor. You may need to take repeated treatment or undergo other treatments to completely clear up the condition.


Normally, a diagnosis of Pityriasis Versicolor is made clinically by observing its appearance and the signs and symptoms of the disease. However, it is also possible to confirm the diagnosis by direct microscopic examination. The most sensitive diagnostic test is CSB staining of skin scrapings. This technique provides rapid and qualitatively superior images than the KOH mount. The CSB stain is a new contrast stain that demonstrates fungal spores and vascular patterns, which are the hallmarks of pityriasis.

The lesions of Pityriasis Versicolor typically appear raised and erythematous with a fine scaling that covers normal skin markings. They may take weeks to months to clear up. During this time, the pigmentation of the lesions is likely to change. The lesions can become darker or lighter, depending on the thickness of the scales. They can also coalesce in extensive areas.

If the patient has a severe case, oral treatment may be considered. The condition is more common in tropical countries. It is most likely to affect adolescents and young adults, although it can also occur in the elderly. Despite its benign nature, patients often find themselves frustrated by the persistent marks.

Pityriasis Versicolor can be caused by a variety of fungi. It is generally considered to be a superficial fungal infection of the stratum corneum. The most commonly identified fungus is Malassezia. The organism can be transmitted directly or indirectly through contaminated bedding and clothing. The pathogen can grow and spread more rapidly and extensively than usual, but it is not always clear why the organism grows.

In some cases, the skin is genetically predisposed to pathogenic conversion. In other cases, immunodeficiency, stress, heat, or an oily skin surface are the factors that lead to the onset of PV. Fortunately, most people are able to ward off the fungus without problems.

The Pityriasis Versicolor sign, which is a stretch of skin surrounding a suspected lesion, was developed by Brazilian dermatologist Zireli de Oliveira Valencia. He presented his findings at the III World Congress of Tropical Dermatology in 1974 in Sao Paulo. He was later awarded the Nobel Prize for Medicine in 1979.

Another diagnostic technique that is useful for the study of PV is the wood lamp. It is useful for diagnosing the affected area, as Malassezia furfur lesions are characterized by a pale yellow fluorescence under the wood’s lamp. Approximately one-third of the cases can be diagnosed using wood lamps. The wood lamp is also useful for assessing the severity of the disease.

Diagnosis of pityriasis may be made by indirect microscopic examination, which involves taking skin scrapings from the affected area. These scrapings are then placed on a potassium hydroxide (KOH) mount. The lesions are then stained with either methylene blue or ink blue. A KOH mount lacks color contrast and sensitivity, so a CSB stain is preferred.


Fortunately, Pityriasis Versicolor is easily treatable. This is because the infection is caused by a fungus. It is also not contagious. There are various treatments that can be used to treat this skin condition. These include topical creams and lotions, oral medicines, and systemic treatment. These treatments are effective in relieving the symptoms and preventing the return of the infection.

The most common type of Pityriasis Versicolor treatment is using topical antifungal agents. These are used to fight the fungus and can be purchased over the counter. These medicines usually contain ketoconazole, pyrithione zinc, and selenium sulfide. These medicines can be applied to the affected area twice a week for about a month.

For more severe infections, prescription medicines can be prescribed. These can be taken as tablets or syrups. The use of oral antifungal medication is mainly recommended when there are large areas of the body that are infected. A physician may prescribe this medicine with prior medical authorization. In addition to oral treatments, a medicated skin shampoo can be used twice a week. It is important to remember to wash the infected areas after applying the medicine to avoid spreading the infection.

The most common cause of pityriasis is the presence of Malassezia fungus. These germs grow on the surface of the skin, causing the rash. They are found in normal skin and can be triggered by humid weather and sweating. They can multiply on the skin, causing a rash that looks like a yeast infection. In most cases, the infection clears up after a few weeks. However, if it does not, a second treatment may be necessary. If you are suffering from pityriasis, you should improve your hygiene by cleaning the infected area with a medicated cleanser. This will help prevent the growth of yeast.

The first line of treatment for pityriasis is selenium sulfide. This is a substance that is often present in soaps, and it has been reported to prevent the return of the disease. Another option is a medicated skin shampoo, which can be applied twice a week for several months. A dermatologist can make the diagnosis of pityriasis by looking at the skin patches and making a direct observation under a microscope.

The length of time a patient will need to use a topical antifungal treatment is determined by the severity of the infection. The treatment can last for up to a month, although it can be longer if the infection recurs. In most cases, the signs of pityriasis fade after about eight to twelve weeks.

When treating Pityriasis Versicolor it is important to keep the infected area clean and dry. During this time, you should also try to limit the amount of oil on your skin. People who have oily skin are more likely to develop the infection.
