Poikiloderma
Poikiloderma is a skin condition that consists of areas of hypopigmentation, hyperpigmentation, telangiectasias and atrophy.
Poikiloderma is most frequently seen on the chest or the neck, characterized by red colored pigment on the skin that is commonly associated with sun damage.
Health Risks
It is a condition that may present a cosmetic nuisance, yet it poses no health risks on its own.
Pathogenesis
The exact cause of poikiloderma is unknown; however, extended sun exposure, namely the ultraviolet light emitted by the sun, is the primary factor.
