A congenital disorder characterized by the complete or partial absence of pigment in the skin, hair, and eyes is called what?

• A. Eczema
• B. Melanoma
• C. Rosacea
• D. Albinism

Answer: (D)

Albinism is a congenital condition where melanin production is defective, leading to little or no pigment in the skin, hair, and eyes. Melanin gives color and helps protect skin from UV radiation, and its production relies on enzymes and genes; when these are defective from birth, pigment is greatly reduced or absent. This results in very light skin and hair, and light-colored eyes with potential vision issues and sensitivity to light. Eczema, melanoma, and rosacea are not about congenital pigment absence: eczema is an inflammatory skin condition, melanoma is a cancer of pigment-producing cells, and rosacea is a chronic facial redness condition.
