The fungus condition tinea versicolor is typically associated with skin discoloration. White, yellow, red, pink, or brown patches of skin may appear on tinea versicolor patients.
The cause of the problem is an overgrowth of a type of yeast (fungus) that is normally prevalent on your skin. Tinea versicolor may become more severe in the presence of sunlight, sweltering heat, and humidity.
It is not harmful or contagious, despite the fact that it can occasionally be a little itchy. On the upper chest, back, and shoulders, tinea versicolor frequently manifests.
To treat the condition, doctors give patients oral or topically applied antifungal medications. It's not necessary to have a prescription to buy some medicines. Following the treatment, the majority of people with tinea versicolor recover fully. Tinea versicolor also known as Pityriasis Versicolor.
Malassezia-genus fungi's mycelial development is what leads to pityriasis versicolor.
The normal skin microbiota, or group of bacteria that live on normal skin, includes malassezia. Lipid is necessary for their survival. Malassezia has been classified into 14 distinct species. The most frequently grown species from P. versicolor are M. globosa, M. restricta, and M. sympodialis.
In the seborrheic areas (scalp, face, and chest), Malassezia typically grows sparsely without producing a rash. It is unknown why they sporadically proliferate more vigorously on the skin's surface to produce pityriasis versicolor. A tryptophan-dependent metabolic pathway is one hypothesis.
The yeasts make basal melanocytes' melanosomes (pigment granules) larger in cases of brown pityriasis versicolor.
Scrapings from this type of pityriasis versicolor make it simpler to show the presence of yeasts than scrapings from the white variety.
The Malassezia-produced chemical is assumed to be the cause of the white or hypopigmented form of pityriasis versicolor because it diffuses into the epidermis and interferes with the melanocytes' ability to create pigment.
The pink variety of pityriasis versicolor has minor dermatitis brought on by Malassezia or its byproducts.
The most obvious sign of tinea versicolor is discolored patches of skin, which most frequently appear on the arms, chest, neck, or back. These patches could be:
Dry, itchy, and scaly skin that is more noticeable and more likely to be absent from tanning in cooler, less humid conditions. Skin that is lighter (more common) or darker than the surrounding skin that is pink, red, tan, or brown.
People with dark skin who acquire tinea versicolor may experience hypopigmentation or a loss of skin color. Some people may experience skin darkening rather than whitening which is known as Hyperpigmentation.
Some people who have tinea versicolor don't notice any noticeable changes to their skin tone or look.
You can suffer itchy skin in addition to alterations in the color of your skin.
Some illnesses with overlapping symptoms, like vitiligo, are frequently confused with tinea versicolor. Vitiligo, however, can be distinguished from tinea versicolor in a number of obvious ways, including:
Your risk for this disorder may increase due to a number of environmental and biological variables, such as:
A clinical diagnosis of pityriasis versicolor is typical. The tests listed below might be beneficial.
Topical antifungal medications are used to treat mild pityriasis versicolor such as:
Itraconazole and fluconazole, two oral antifungal medications, are used to treat pityriasis versicolor when the disease is severe or when topical medications have failed.
An hour after taking the medication, you might benefit from a strong workout to help you sweat it onto your skin's surface, where it can remove the yeast in an efficient manner. For a few hours, you should refrain from taking a bath.
Many cases of pityriasis can be permanently resolved, or at least controlled, with a few days of treatment.
For yeast infections like pityriasis versicolor, oral terbinafine, an antifungal drug used to treat dermatophyte infections, is ineffective.
Your doctor may recommend a once- or twice-monthly cutaneous or oral therapy to help prevent tinea versicolor from reoccurring. These may only be necessary to use during the hot, humid months. Preventive measures include:
