Phytophotodermatitis: a visit to Margaritaville.

Phytophotodermatitis is a phototoxic eruption following contact with photosensitizing compounds and long-wave ultraviolet light. The most common phototoxic compounds are the furocoumarins contained in a wide variety of plants, especially of the Umbelliferae, Rutaceae, and Moracea families. Commonly occurring photosensitizing plants include citrus fruits such as limes and oranges and many vegetables, notably celery, parsnip, parsley, carrots, and dill.
