Tinea Versicolor Treatment St. Louis
Tinea versicolor is a common fungal infection that causes patches of discolored skin. It can affect people of all ages and is caused by the overgrowth of a yeast called Malassezia on the skin's surface. This type of fungal infection, also known as pityriasis versicolor, is often mistaken for other dermatologic disorders such as seborrheic dermatitis or atopic dermatitis. The yeast, Malassezia spp., is a part of normal skin flora but can multiply rapidly under certain conditions, leading to the appearance of patches on the skin.
At Mid-County Dermatology in St. Louis, MO our board-certified dermatologists encounter this problem often, especially during summer. Read below to learn more about tinea versicolor and schedule an appointment if you think you may have this rash.
What is Tinea Versicolor?
Tinea versicolor, also known as pityriasis versicolor or simply versicolor, is a fungal infection caused by yeast on the skin. This condition results in uneven skin pigmentation and can be quite bothersome for those who experience it. It's important to note that tinea versicolor is not contagious, but it can be recurrent, meaning it may come back even after treatment.
Fungal infection caused by yeast on the skin
Tinea versicolor is caused by a type of yeast called Malassezia. This yeast naturally lives on our skin and usually doesn't cause any harm. However, certain factors such as hot and humid weather, oily skin, hormonal changes, weakened immune system, or excessive sweating can create an environment where the yeast overgrows and leads to tinea versicolor.
When the yeast overgrows, it interferes with the normal pigmentation process of the skin. This results in patches of lighter or darker coloration on the affected areas. These patches are often more noticeable when you have a tan because the affected areas do not tan like the rest of your skin.
Results in uneven skin pigmentation
One of the main characteristics of tinea versicolor is its impact on skin pigmentation. The patches caused by this condition can vary in color from light pink to brown or even white. They often appear on areas such as the chest, back, shoulders, neck, and upper arms.
The uneven pigmentation can be quite distressing for individuals who have tinea versicolor. It may affect their self-confidence and cause them to feel self-conscious about their appearance. However, it's important to remember that tinea versicolor is a common condition that affects people of all ages and races.
Not contagious but can be recurrent
Unlike some other fungal infections like ringworm or athlete's foot which are highly contagious, tinea versicolor is not contagious. You cannot catch it from someone else or spread it to others through direct contact.
However, even though tinea versicolor is not contagious, it can be recurrent. This means that even after successful treatment and clearance of the patches, there is a possibility for the condition to return in the future. Factors such as those mentioned earlier, like hot weather or hormonal changes, can trigger a recurrence of tinea versicolor.
Causes and Risk Factors
Tinea versicolor is caused by an overgrowth of yeast on the skin's surface. This yeast, known as Malassezia furfur, is naturally present on the skin but can multiply rapidly under certain conditions. Warm and humid environments provide the perfect breeding ground for this yeast to thrive.
One of the key risk factors for tinea versicolor is having oily skin. The excess oil on the skin creates an ideal environment for the yeast to grow and spread. Individuals with weakened immune systems are more susceptible to developing tinea versicolor. This includes people with conditions such as HIV/AIDS or those taking immunosuppressive medications.
Several studies have shown a correlation between tinea versicolor and sun exposure. It has been observed that individuals who spend a lot of time in the sun, especially in hot and humid climates, are more likely to develop this condition. Sun exposure can alter the pigmentation of the skin, leading to patches or plaques that are lighter or darker than surrounding areas.
The pathogenic role of Malassezia furfur in tinea versicolor has been extensively studied. Research has demonstrated that this yeast produces substances that interfere with melanin production in the skin cells, resulting in discoloration. Moreover, these substances can also trigger an inflammatory response in some individuals, leading to itching and discomfort.
Tinea versicolor tends to recur in many cases, particularly when exposed to warm and humid conditions again. The yeast can persist on clothing or other surfaces even after treatment, making it easier for reinfection to occur.
Immunocompromised patients face additional challenges when dealing with tinea versicolor. Their weakened immune systems may be unable to effectively fight off the infection, leading to more severe symptoms and a higher likelihood of recurrence.
It is important to note that while tinea versicolor is a common condition affecting people worldwide, it does not pose any serious health risks. However, it can cause distress and affect one's self-esteem due to the visible nature of the skin lesions.
Common Symptoms of Tinea Versicolor
Patches of lighter or darker skin than usual
One common symptom of tinea versicolor is the presence of discolored patches on the skin. Depending on the individual, these patches can appear lighter or darker than the surrounding skin. It's like having a patchwork quilt on your body! The affected areas may have a mottled appearance, resembling small islands amidst normal skin.
Itching or scaling may occur in affected areas
Another telltale sign of tinea versicolor is itching or scaling in the affected areas. Imagine having an itch that just won't go away, and when you scratch it, little flakes start coming off! This can be quite bothersome and uncomfortable for those experiencing it. The itching sensation may vary in intensity from mild to severe, depending on the person.
More noticeable after sun exposure due to lack of tanning
The symptoms of tinea versicolor often become more noticeable after sun exposure because the affected areas do not tan like the rest of the skin. So while everyone else is getting that golden summer glow, you're left with these stubborn patches that refuse to change color! It's almost like having your own personal sunblock built into your skin.
Discolored patches may be macules or papules
The discolored patches caused by tinea versicolor can take different forms. They are commonly seen as either macules or papules. Macules refer to flat and distinct discolored spots on the skin, while papules are raised and can sometimes be felt as small bumps when touched. So depending on how your tinea versicolor presents itself, you might have either smooth spots or tiny raised bumps.
Affected areas often found on chest, back, neck, and arms
Tinea versicolor tends to favor certain areas of the body. You'll usually find these discolored patches on the chest, back, neck, and arms. It's like having a secret code written on your skin that only tinea versicolor knows! These areas provide the perfect environment for the yeast that causes this condition to thrive.
Diagnosing Tinea Versicolor
To diagnose tinea versicolor, healthcare professionals employ various methods to determine the presence of this fungal infection on the skin. These techniques help identify the characteristic signs and symptoms associated with the condition.
Visual Examination by a Dermatologist
One way to diagnose tinea versicolor is through a visual examination conducted by a dermatologist. They carefully inspect the affected area, looking for specific characteristics that indicate the presence of this fungal infection. The healthcare provider will observe any discoloration, scaling, or patches on the skin that are typical of tinea versicolor.
Use of a Special Ultraviolet Light to Detect Fluorescence Patterns on the Affected Area
In some cases, dermatologists may use a special ultraviolet light called a Wood's lamp during the diagnosis process. This lamp emits ultraviolet (UV) light that can reveal fluorescence patterns on the affected area of the skin. Under UV light, areas affected by tinea versicolor may appear yellowish-green or coppery in color. This fluorescence can help confirm the diagnosis.
Skin Scraping for Microscopic Analysis
Another method used to diagnose tinea versicolor involves taking a skin scraping from the affected area and analyzing it under a microscope. The healthcare professional gently scrapes off some scales from the skin surface using a blunt edge or scalpel blade. They then prepare a potassium hydroxide wet mount slide with these collected samples.
Microscopic examination allows for closer inspection of the scraped skin cells and fungal elements present in them. Potassium hydroxide (KOH) helps dissolve keratinized cells, making it easier to visualize any fungal hyphae or spores under high magnification using a microscope. The presence of these fungal elements confirms the diagnosis of tinea versicolor.
Treatment Options for Tinea Versicolor
Tinea versicolor, a common fungal infection of the skin, can be effectively treated using various methods. Here are some treatment options to consider:
Antifungal creams, lotions, or shampoos applied topically
Topical antifungal therapy is often the first line of treatment for tinea versicolor. These medications come in creams, lotions, or shampoos that are applied directly to the affected areas of the skin. Some commonly used topical antifungals include:
Selenium sulfide: This ingredient helps to control the growth of the fungus and reduce inflammation.
Zinc pyrithione: Known for its antifungal and antibacterial properties, zinc pyrithione helps eliminate the fungus causing tinea versicolor.
Ketoconazole: A broad-spectrum antifungal agent that inhibits fungal cell growth and treats tinea versicolor effectively.
By applying these topical treatments as directed by a healthcare professional, you can help clear up the infection and prevent future outbreaks.
Oral antifungal medications prescribed in severe cases
In more severe cases or when topical treatments fail to provide sufficient relief, oral antifungal medications may be prescribed. These medications work from within your body to combat the fungal infection. Commonly prescribed oral antifungals for tinea versicolor include:
Fluconazole: This medication is taken orally for several weeks to eradicate the fungus causing tinea versicolor.
Itraconazole: Similar to fluconazole, itraconazole is taken orally over a period of time to treat moderate to severe cases of tinea versicolor.
It's important to note that oral antifungal medications may have potential side effects and should only be taken under medical supervision.
Maintaining good hygiene and avoiding excessive sweating
Besides using medication, maintaining good hygiene practices can help prevent the recurrence of tinea versicolor. Here are some tips to follow:
Keep your skin clean and dry: Regularly wash and dry the affected areas, ensuring they are completely dry before applying any topical treatments.
Avoid excessive sweating: Excessive sweating can create a favorable environment for fungal growth. Wear breathable clothing and avoid activities that cause excessive perspiration.
Use antifungal soaps or cleansers: Incorporating antifungal soaps or cleansers into your bathing routine can help keep the fungus at bay.
By practicing good hygiene habits and taking precautions to minimize sweating, you can reduce the chances of tinea versicolor returning.
