How Is Tinea Versicolor Diagnosed
See your doctor if strangely colored patches develop on your skin and you cant treat them at home. Your doctor will examine your skin and may be able to tell if you have tinea versicolor just by looking at the patches.
If a diagnosis cant be made by looking at the skin, your doctor may take a skin scraping. A skin scraping removes cells from your skin for testing by scraping the skin gently. The cells are viewed under a microscope to see if they contain the yeast that causes this condition. Your doctor can conduct a potassium hydroxide microscopy. In this procedure, your doctor takes a skin sample, places it on a microscope slide with a solution of 20 percent KOH, and looks for yeast or hyphae fungi under a microscope.
Your doctor might also take a biopsy, or tissue sample, of the affected skin and test for fungi on the outer skin layer. A sample of the fungus on the skin can also be tested in a fungal culture to see if you have the condition.
Your doctor may also use a Woods lamp to look at your skin. This special machine, which uses ultraviolet light, is held 4 to 5 inches from your skin. If yeast is present, the affected skin will appear yellow or green under the light.

Red Itchy Skin Is A Symptom Of More Than One Health Condition
Is your skin red, itchy, inflamed, or painful?
These symptoms can indicate a host of skin conditions, including rosacea, dyshidrotic eczema, contact dermatitis, ringworm, impetigo, pityriasis rosea or rubra, actinic keratosis, tinea versicolor, cellulitis, and seborrhea.
Many skin conditions have no known cause, while others are due to such disparate causes as sun exposure or genetics. A few, like ringworm and impetigo, are the result of your skin coming into contact with a microorganism, like a fungus or certain bacteria.
Jeffrey Weinberg, MD, a board-certified dermatologist and associate clinical professor of dermatology at Mount Sinai in New York City, says all of these conditions are treatable and generally not life-threatening. He adds that while a majority of skin conditions at least those not related to an infection are never completely cured, most can be managed.

If you have questions or concerns talk to your primary care provider. Skin discoloration can be triggered by a variety of causes, so check with your doctor for a diagnosis and treatment options.
What causes white dry patches on skin?
The most common causes of dry white patches on the skin are eczema, seborrheic dermatitis, psoriasis and nutritional deficiencies.
Eczema is a chronic, probably genetic, inflammatory skin condition that causes the skin to become inflamed or irritated and often results in a patch of skin that is lighter in pigment than the skin around it.
Eczema is especially common in children, says Dr. Wilson. They often outgrow it, but some people continue to have symptoms on and off throughout their lives.
Eczema is always itchy, and sometimes itching will start before a rash appears, most often on the face, back of knees, wrists, hands or feet. The areas may appear dry, thickened or scaly, and sometimes the skin can blister. Many people with eczema have allergies as well.
The right treatment will depend on your age, medical history and severity of your symptoms, says Dr. Wilson. Your doctor can determine what is best for you.

However, even after eliminating the infection, your skin may remain discolored for several weeks or months following treatment. Your infection may also return when the weather becomes warmer and more humid. If your condition returns, your doctor may prescribe medication once or twice per month to prevent symptoms.
It can be difficult to prevent a recurrence of this condition. If youve been diagnosed with tinea versicolor and youve successfully treated it, there are steps you can take to prevent future infections. These include:
- avoiding excessive heat
- avoiding tanning or excessive sun exposure

There Are A Few Things To Know About Eczema In Melanin
Eczema can get overlooked in darker skin types because it often presents differently than it does in lighter skin, in which it tends to be red and very visible. In darker skin, the redness is not as apparent and the skin may even look normal even though it feels very itchy. Eczema in darker skin can also have a dark brown or purplish appearance.
Theres one type of eczema that you see a lot in people with darker skin types: follicular eczema. This is the type of eczema I experienced early on, before it flared in different ways during my first pregnancy. Follicular eczema doesnt really look like a rash instead, it looks like goosebumps or small bumps around hair follicles throughout different areas of the body, including the back, abdomen, thighs, and chest. As a dermatologist, a lot of parents bring their kids into my office wondering why their kids skin is so dry and bumpy. The skin in these patients may not even be itchy, but it lets me know that they may have eczema and we should practice very gentle skin care with them to reduce the risk of a visible flare.

How Do Brown Skin Spots Develop
As shown above, brown patches on the skin can take many different forms: from small and sharply defined to large and frayed. They appear individually or in groups, some are a little raised, but most are completely smooth. These brown discolorations can occur basically anywhere on the body. They can be congenital or develop only in the course of life
Responsible for such brown discolorations on the skin is usually a local overproduction of the pigment melanin , which gives our skin, hair and eyes the actual color. Other causes can be:
- smallest bleedings in the legs due to vein weakness
- Metabolic disorders e.g. due to liver disease
- Systemic diseases or hereditary diseases
- Contact with chemical substances such as silver salts or phenols
In addition, there are various factors that can promote an overproduction of melanin: The most important are sunlight, genetic predisposition, metabolism, hormonal influences, ageing processes and skin injuries. Certain drugs may also play a role.

How Different Skin Types Are Affected
The features of eczema differ depending on the persons skin type.
On paler skin, the typical pattern is inflamed, red or dark pink patches, with dry itchy skin, which in severe flares may ooze with small vesicles .
On darker skin, inflammation is more difficult to detect, as it is seen as various stages of hyper-pigmentation and is more subtle, so often redness is not seen. As a result, the severity of eczema can be underestimated.
Post-inflammatory hypo- and hyper-pigmentation are a much greater concern in people with darker skin, as it can take months for this to resolve and the discoloration can sometimes be a greater concern than the eczema itself.
Another feature of eczema, more commonly found in darker skin, is follicular prominence. This is where the eczema appears in small, itchy bumps or papules on the skin mainly on the trunk and forearms. Dry skin and scale can also be more prominent, as its white or grey colour shows up most noticeably.
A UK longitudinal study into ethnic variations in atopic eczema reported that children with darker skin were more likely to develop atopic eczema than their white counterparts and were six times more likely to develop severe eczema.

What Causes Mongolian Blue Spots
Mongolian blue spots appear on the skin at or shortly after birth. The spots appear when melanocytes remain in the deeper skin layer during embryonic development. What causes this to happen isnt known. Mongolian blue spots arent related to an underlying health condition.
Sometimes the spots are mistaken for symptoms of a common spinal condition called spina bifida occulta. However, according to the Spina Bifida Association, related spots are red not the grayish color of Mongolian blue spots.
