Solar Dermatitis
(Sunburn)

Description : The ultraviolet Type B rays emitted by the sun are responsible for both acute and chronic skin damage. Two types of fair-skinned individuals are the most susceptible to solar damage: the Type 1 individuals who always burn and never tan and the Type 2 individuals who usually burn and only tan lightly and with difficulty.

When susceptible skin is exposed to the sun's rays, the initial damage appears as localized erythema confined to the exposed areas. With more prolonged exposure, blisters, vesicles, and blebs will form. The resultant irritation often leads to scratching and subsequent secondary infection.

In individuals with short hair or outstanding ears, the superior surface of the pinna is likely to be burned, since it is unprotected and exposed to the sun's rays.

The superior portion of the pinna shows erythema with edema and blistering, as the result of a "second-degree" sunburn.
