Phytophotodermatitis due to figs.

Abstract

Phytophotodermatitis is an acute skin reaction that may be easily confused with other causes of contact dermatitis. It is characterized by sunburn, blisters, and/or hyperpigmentation. The reaction takes place when certain plant substances known as psoralens, after being activated by ultraviolet light from the sun, come in contact with the skin. The condition is usually mild and self-limited but hyperpigmentation may persist for many weeks. Failure to recognize phytophotodermatitis in a child may lead to a mistaken diagnosis of child abuse. It is also important to be aware of perfumes and grocery products as causes of this phenomenon.
