How does Tinea versicolor affect the skin's pigmentation?

Tinea versicolor is a fungal skin condition caused by an overgrowth of yeast that is normally found on the skin. This condition affects the skin’s pigmentation by resulting in small, discolored patches that can be lighter or darker than the surrounding skin. The patches may appear white, tan, pink, or brown, depending on the individual's skin tone and the extent of the fungal overgrowth.

This variation in skin color occurs because the fungus interferes with the normal production of melanin, the pigment responsible for skin color. As a result, the affected areas do not tan properly and can contrast with the skin around them, leading to patches that may be more prominent in sunlight.

In contrast to the other options, which do not accurately describe the primary effects of tinea versicolor, the correct choice captures the essence of how the condition manifests on the skin. The condition does not typically cause yellow discoloration, inflammation, or an overall darkening of the skin, but rather these distinct patches are a hallmark sign of the fungal imbalance affecting pigmentation.
