What condition results from a decrease in melanocyte activity?

1. Hyperpigmentation

2. Leukoderma

3. Eczema

4. Psoriasis

The correct answer is: Leukoderma

The correct answer focuses on leukoderma, which is a condition characterized by a loss of skin pigmentation. This condition arises specifically from a decrease in the activity of melanocytes, the cells responsible for producing melanin, the pigment that gives skin its color. When melanocyte activity decreases, there is less melanin in the skin, leading to lighter patches or areas devoid of color, which can resemble white spots or depigmented areas. Understanding leukoderma helps clarify its relationship with other skin conditions. Hyperpigmentation, by contrast, occurs when there is an increase in melanin production, leading to darker patches on the skin. Eczema and psoriasis are inflammatory skin conditions that involve various symptoms such as redness, itching, and scaly patches, but they are not directly related to melanocyte activity. Therefore, when considering conditions resulting from decreased melanocyte function, leukoderma is the accurate choice.
