Tinea versicolor is a fungal infection of the topmost layer of the skin causing scaly, discolored patches.

• This infection is caused by a type of fungus.

• Typically, people have scaly patches of skin.

• The diagnosis is based on appearance and skin scrapings.

• This infection often returns.

• Antifungal skin products, shampoos, and sometimes drugs taken by mouth are used to treat the infection.

(See also Overview of Fungal Skin Infections Overview of Fungal Skin Infections Fungi usually make their homes in moist areas of the body where skin surfaces meet: between the toes, in the genital area, and under the breasts. Common fungal skin infections are caused by… read more .)

The infection is caused by Malassezia furfur and is quite common, especially among young adults. Malassezia furfur is a type of fungus that can exist as both a yeast and a mold. Yeast and mold are terms that are used to describe what the fungus looks like under a microscope.

Malassezia furfur is typically harmless and normally lives on the skin but in some people causes tinea versicolor. Most affected people are healthy. Some people may be genetically predisposed to overgrowth of this fungus.

Other risk factors for tinea versicolor include heat and humidity and an immune system weakened by corticosteroid use, pregnancy, undernutrition, diabetes, or other disorders.

Tinea versicolor is a mild infection and is not considered contagious.

Tinea versicolor causes many tan, brown, salmon, or white scaly patches to appear on the trunk, neck, abdomen, and occasionally the face. The patches may join to form larger patches. The patches do not tan, so in summer, when the surrounding skin tans, the patches may become obvious. People with naturally dark skin may notice lighter patches. People with naturally fair skin may get darker or lighter patches. Tinea versicolor usually does not cause other symptoms.

The skin may not regain its normal pigmentation for many months or years after the infection is gone.

Tinea versicolor commonly comes back after successful treatment because the yeast that causes it normally lives on the skin.

Any antifungal drugs applied directly to the affected areas (topical) may be used to treat tinea versicolor. Prescription-strength selenium sulfide shampoo is effective if applied to affected skin (not just the scalp) for 10 minutes a day for 1 week or for one 24-hour application each week for one month. Other treatments include applying topical ketoconazole daily for 2 weeks and bathing with zinc pyrithione soap or applying sulfur-salicylic shampoo to the skin daily for 1 to 2 weeks. (See also table Some Antifungal Drugs Applied to the Skin (Topical Drugs) Some Antifungal Drugs Applied to the Skin (Topical Drugs) .)

Antifungal drugs taken by mouth, such as fluconazole, are sometimes used to treat people who have a widespread infection ( see Table: Drugs for Serious Fungal Infections Drugs for Serious Fungal Infections ) or frequent infections.

To lower the chance of the infection coming back, many doctors recommend practicing meticulous hygiene and using zinc pyrithione soap regularly or one of the other topical treatments monthly.

What is tinea versicolor and what are the symptoms?

A common skin infection, tinea versicolor is caused by a type of fungus that lives on the surface of the skin and feeds on the natural oils produced by the skin.

Pityriasis versicolor – Medina Medical Center +

Pityriasis versicolor (Pityriasis versicolor, as well as beach pityriasis) refers to fungal diseases of the skin. It mainly affects young people between the ages of 14 and 40. As a result, it practically does not occur in children under 7 years of age.

Causes of pityriasis versicolor.

As a consequence, the main causative agent of pityriasis versicolor is a fungus of the genus Pityrosporum orbiculare. It belongs to opportunistic pathogens and is present on the human skin as part of the normal microflora.
The fungus can become pathogenic and cause disease:

• First, if there is excessive sweating
• Second when taking oral contraceptive hormones antibiotics for a long time
• Thirdly, when the pH of sweat changes to the alkaline side

Symptoms of pityriasis versicolor.

The main symptom of pityriasis versicolor is spots of various sizes, oval or round in shape with uneven edges, localized on the skin of the upper part of the body (stomach, chest, neck, as well as shoulders, arms, back, groin, etc.). ).

Lichen is almost never localized on the soles of the feet and hands. Pityriasis versicolor patches on untanned skin can be various shades of creamy pink, brown, yellow, or red. Moreover, different spots can have a different color, as a result of which the disease received one of its names – versicolor versicolor. On tanned skin, the spots become white in color and are very flaky.

Moreover, the greater the amount of sunlight received by the skin, the whiter the spots become and the more they peel off. Pityriasis versicolor patches may itch moderately or mildly. Over time, without treatment, more and more areas of the skin are affected and a pronounced cosmetic defect occurs.

Diagnosis of pityriasis versicolor.

Pityriasis versicolor is often immediately diagnosed at a dermatologist’s consultation during examination and dermatoscopy of discolored skin areas. To confirm the diagnosis, the Balzer iodine test is performed.
Luminescent diagnostics, carried out in a special darkened room, reveals red-yellow or dark brown fluorescence spots. Microscopic examination of scrapings with pityriasis versicolor allows you to detect elements of the fungus in the scales of the epidermis.

Treatment of pityriasis versicolor.

Treatment is carried out on an outpatient basis until the symptoms of pityriasis versicolor disappear completely. Local antifungal agents are used: 5% salicylic ointment, 3-5% salicylic alcohol, as well as terbinafine, bifonazole, clotrimazole, cycloperox, etc.

Prevention.

Prevention of recurrence of pityriasis versicolor includes repeated antifungal treatment, regular water treatments and therapy for hyperhidrosis.

If such symptoms appear, it is necessary to consult a dermatologist, who will conduct diagnostic tests, microscopy of scrapings from spots, iodine test, Wood’s lamp examination and prescribe treatment.

PANTIBROUS > Read the publications of doctors of the MEDIAN clinic ia. It mostly worsens in the spring. It is characterized by a long course, damage to the epidermal layers of the skin with the appearance of spots of different colors on it. This disease is also called colored or multi-colored. In the people, the disease is called solar lichen. The disease is ubiquitous, but most common in regions with a hot and humid climate. Mostly people of young and middle age are ill, it is extremely rare – children and the elderly.

This disease begins with the appearance on the skin of small spots the size of a pinhead, which in different patients have the most pink spots, and then yellow or brown, light brown (hence the name – multi-colored lichen). Spots tend to merge to form large foci, but can exist in isolation. There are no inflammatory phenomena, there is a slight scaly peeling (due to loosening of the stratum corneum by the fungus). Only the stratum corneum of the epidermis is affected.

Causes of pityriasis versicolor.

The fact is that the fungus of the genus Malassezia is always present in the human body. However, it is activated under certain conditions, for example, with vegetative-vascular diseases, with a decrease in immunity, with an increase in oily skin and sweating. Basically, the disease appears on a tanned body. Spots on the neck, back, thighs, abdomen, on the forearms are the color of coffee with milk.

This disease can be transmitted through personal hygiene through clothing, towels, bedding. Pityriasis versicolor is not aggressive, but at its first manifestations, it is necessary to seek help from a dermatologist as soon as possible. If the disease is started, the skin will acquire a leopard color for a very long time.

To diagnose pityriasis versicolor, the following is performed:

Iodine test (Balser test), for this, the affected skin is smeared with iodine tincture and immediately wiped with alcohol (the latter is optional; mandatory): the stratum corneum loosened by the fungus quickly absorbs iodine and spots of pityriasis versicolor stand out sharply, turning dark brown against the background of slightly yellowed, undamaged skin. In the absence of iodine solution, aniline dyes can be used.

Skin scraping, when viewed under a microscope, should show yeast.

Under a Wood’s fluorescent lamp in a darkened room, cells

versicolor give a reddish-yellow, greenish-blue or brown

glow.

How is pityriasis versicolor treated?

The dermatologist must select the appropriate treatment. As a rule, the treatment of multi-colored lichen in humans occurs with the help of sprays, ointments, solutions. If the spots are spread over a wide area of ​​the skin, then most likely the doctor will prescribe a course of pills.
