2. Tinea Versicolor
also known as Pityriasis versicolor, is a common fungal infection of the
skin. It's caused by an overgrowth of yeast (Malassezia species) that
naturally lives on the skin. The infection leads to the development of
discolored patches of skin.
Pityriasis versicolor affects the trunk, neck, and/or arms, and is uncommon on other
parts of the body. The patches may be coppery brown, paler than surrounding skin, or
pink. Pale patches may be more common in darker skin; this appearance is known as
pityriasis versicolor alba. Sometimes the patches start scaly and brown, and then
resolve through a non-scaly and white stage.
Pityriasis versicolor is usually asymptomatic, but in some people it is mildly itchy.

3. Symptoms:
• Discolored patches of skin, which may be lighter or darker
than the surrounding skin.
• Patches can become more noticeable after sun exposure
because the fungus prevents the affected skin from tanning.
• Mild itching might be experienced.
• Common areas affected include the back, chest, and
shoulders, but it can also appear elsewhere.

4. Causes:
The yeast responsible for tinea versicolor
(Malassezia) is a normal inhabitant of the skin.
Factors that can promote its overgrowth and lead to
tinea versicolor include:
• Hot, humid weather
• Oily skin
• Hormonal changes
• Weakened immune system

5. Diagnosis:
• Wood lamp (black light) examination. use ultraviolet light, which may make the
affected areas appear a fluorescent coppery orange color if they're the result of
tinea versicolor.
• Microscopy using potassium hydroxide (KOH). removes cells from your skin,
soaks them in potassium hydroxide, then looks at them under a microscope.
• Skin biopsy. takes a skin sample by scraping some skin and scales from the
affected area to look at under a microscope. With children, the doctor may lift
off skin cells by first firmly attaching clear tape to the affected area then
removing it. The sample then can be stuck directly onto a slide to look at with a
microscope.

6. Treatment:
• Topical antifungal treatments: Over-the-counter (OTC) or prescription-
strength antifungal creams, lotions, or shampoos (such as
ketoconazole, clotrimazole, or selenium sulfide) can be effective.
• Oral antifungal medications: For more widespread infections or those
that don't respond to topical treatments, oral antifungal medications
(like fluconazole or itraconazole) might be prescribed.
• Recurrence: Tinea versicolor can return, especially in warm, humid
climates. Regular use of antifungal products or periodic treatments can
help prevent recurrence.

8. After Treatment:
It's important to note that even after successful treatment, the color
change of the skin can remain for weeks to months, especially in those
with darker skin tones. Over time, the skin color should return to its
natural shade.
