TV in skin most likely refers to tinea versicolor, a common fungal infection that affects the skin's pigmentation.
Understanding Tinea Versicolor
Tinea versicolor occurs when a type of yeast (fungus) called Malassezia grows out of control on the skin's surface. This fungus interferes with the normal pigment production, leading to the characteristic discolored patches.
Symptoms
- Discolored Patches: Patches can be lighter (hypopigmentation) or darker (hyperpigmentation) than the surrounding skin. They can be pink, red, tan, or brown.
- Location: Commonly found on the trunk, shoulders, neck, and upper arms. It can appear on the face, especially in children.
- Scaling: The patches may be slightly scaly or itchy.
- Appearance: The patches are often more noticeable after sun exposure, as the affected skin does not tan normally.
Causes
- Yeast Overgrowth: Malassezia is a normal part of the skin flora, but it can overgrow under certain conditions.
- Factors that Contribute:
- Hot, humid weather
- Oily skin
- Excessive sweating
- Weakened immune system
Diagnosis
A doctor can usually diagnose tinea versicolor by examining the skin. Sometimes, a skin scraping may be taken and examined under a microscope to confirm the presence of the fungus.
Treatment
Tinea versicolor is typically treated with antifungal medications.
- Topical Treatments: Antifungal creams, lotions, or shampoos containing ingredients like ketoconazole, selenium sulfide, or zinc pyrithione.
- Oral Medications: In more severe or widespread cases, oral antifungal medications may be prescribed.
Prevention
- Keep skin clean and dry.
- Use antifungal shampoo regularly, especially in warm, humid weather.
- Avoid excessive sweating.
Tinea versicolor is generally not contagious, and the discoloration is not permanent, although it can take several months for the skin to return to its normal color after treatment.
