What skin condition indicates an overproduction of pigment?

• A. Vitiligo
• B. Melasma
• C. Albinism
• D. Actinic keratosis

Answer: (B)

The condition that indicates an overproduction of pigment is melasma. This skin disorder is characterized by brown or gray-brown patches on the skin, often occurring on the face. Melasma is frequently associated with hormonal changes, such as those occurring during pregnancy or as a side effect of birth control pills, which can trigger the overproduction of melanin in certain areas of the skin. In contrast, vitiligo involves the loss of pigment due to the destruction of melanocytes, leading to lighter patches on the skin. Albinism is a genetic condition resulting in little to no melanin production, causing very light skin, hair, and eyes. Actinic keratosis, on the other hand, is a pre-cancerous condition caused by sun exposure, presenting as rough, scaly patches, but does not directly involve pigmentation overproduction. Therefore, melasma, with its distinctive patches due to excess pigment, is the correct answer.
