Phytophotodermatitis , also known as " lime disease " (not to be confused with Lyme disease), " Berloque dermatitis " , or " Margarita photodermatitis " is a skin condition caused by a chemical reaction that makes the skin hypersensitive to ultraviolet light. It is often mistaken for hereditary conditions such as atopic dermatitis or chemical burns, but this is caused by contact with photosensitizing compounds - such as furanocoumarins - found naturally in some plants and vegetables such as parsnips, citrus fruits and more. Symptoms include burning sensation, itching and large blisters that slowly accumulate over time. One of the earliest descriptions of the disease was made by Darrell Wilkinson, an English dermatologist in the 1950s.

Symptoms
Symptoms are equivalent to photodermatitis, but vary in severity. Skin condition is skin phototoxic inflammation inflammation caused by contact with light-sensitive botanical materials - especially from the Umbelliferae plant family, Rutaceae, Moraceae, and Leguminosae - and ultraviolet light, usually from sun exposure. Phytophotodermatitis usually results in hyperpigmentation of the skin that often appears like a bruise. It may be accompanied by blisters or burns. The reaction usually begins within 24 hours of exposure and peaks at 48-72 hours after exposure.
Phytophotodermatitis can affect people of all ages. Because of the appearance of such a bruise that is usually in the form of handprints or fingerprints, it can be mistaken in children for child abuse.

Common causes
- Parsnips, parsley, celery, common hogweed, giant hogweed
- Carrots and wild carrots
- Notobubon galbanum (formerly known as Peucedanum galbanum synonym ), South African plant also known as "blister bush", "fennel pork", or locally in Afrikaans as bergseldery (ie "mountain celery")
- Lemon, lime, orange bergamot
- Public roads ( Ruta graveolens ) and other plants in the genus Ruta
- Sclerotinia sclerotiorum , which can infect celery
- General smoke, the sap contains various furocoumarin isomers such as 8-methoxypsoralen, which induce allergic photodermatitis
- Dictamnus (commonly known as "Burning Bush")
- Ambrette Abelmoschus moschatus
Treatment
Phytophotodermatitis can be prevented by staying indoors after handling the above substances. However, the main trigger mechanism is UV-A radiation (320-380m) that windows are not guaranteed to be filtered.
Many different topical and oral medications can be used to treat the phytophotodermatitis inflammatory reaction. Dermatologists can also prescribe bleach creams to help treat hyperpigmentation and restore normal skin pigmentation. If they do not receive treatment, the affected site may develop permanent hyperpigmentation or hypopigmentation.
