In brief: Reaction to sun.

Swelling and itiching that does not stay localized with negative blood tests.
The body reacts to exposure to sunlight. This is distinguished from other conditions which cause sun sensitivity such as lupus. Treatment is antihistamines, sunscreen, and limiting sun exposure.Betacarotene orally can be useful in minimizing symptoms.

In brief: No

No one really knows why sun exposure can trigger hives in sensitive persons.
It is believed to be caused by some unknown ige-mediated allergic reaction that is only triggered in the presence of certain light wave lengths. Treatment is avoidance of prolonged exposure, sunscreens can be effective. In others, high dose antihistamines can help. Car window tinting is also helpful in some persons.
