Sun Sensitivity Disorders

Sun Sensitivity Disorders



Some people develop a rash because their skin is sensitive to sunlight; this is known as photosensitivity. Patients may not associate their skin complaint with the light. It is not always the bright summer sun which is responsible; some people also react to winter daylight, and very sensitive people may even be affected by fluorescent lamps indoors.

Xeroderma Pigmentosum

Xeroderma pigmentosum, or XP, is a very rare inherited disease that causes extreme sensitivity to the sun's ultraviolet rays. Unless patients with XP are protected from sunlight, their skin and eyes may be severely damaged. This damage may lead to cancers of the skin and eyes. XP has been identified in people in every ethnic group all over the world.
