Picture of Phytophotodermatitis Hyperpigmentation
Phytophotodermatitis is a skin condition that results when the skin comes into contact with certain plants and then receives exposure to sunlight inducing an inflammatory reaction. This constitutes a phototoxic reaction due to photosensitizing compounds in several plant families. Limes are a common trigger of this condition. The photo depicts a patient who got oil from the rind of a lime on her hands and subsequently touched her face while sunbathing.
