What is tinea versicolor?

1. A viral infection

2. A fungal infection that inhibits melanin production

3. A bacterial infection

4. A type of eczema

The correct answer is: A fungal infection that inhibits melanin production

Tinea versicolor is indeed a fungal infection that affects the skin, specifically caused by an overgrowth of a type of yeast that is normally found on the skin. This condition disrupts the production of melanin, the pigment responsible for skin color, leading to discoloration in the form of lighter or darker patches on the skin. The disruption of melanin production occurs because the yeast produces dicarboxylic acids, which inhibit the activity of the enzyme responsible for melanin formation. This is why individuals with tinea versicolor may notice changes in skin tone that can be more prominent after sun exposure or tanning. Other options present different types of skin conditions or infections that are not related to tinea versicolor. For example, a viral infection or a bacterial infection would involve different microorganisms and mechanisms altogether. Eczema, which is a chronic inflammatory skin condition, is different in etiology and presentation, often affecting the skin's barrier function rather than producing patches of skin discoloration as seen with tinea versicolor. This highlights the unique nature of tinea versicolor as a fungal-related skin disorder specifically impacting pigmentation.
