Phytophotodermatitis is an acute skin reaction that occurs when certain chemical compounds present in plants or fruit come into contact with the skin and are simultaneously activated by exposure to sunlight or ultraviolet (UV) light. It occurs most frequently in people working in agricultural activities or when gardening.
It is caused by two factors: the presence of phytochemical compounds in certain plants, such as lemon, lime, orange, celery and some flowers, and subsequent exposure to sunlight or ultraviolet light.
Symptoms appear within the first 24 hours after exposure. The most common manifestations include redness, swelling, burning and blistering on the hands, arms, face and neck after exposure to the vegetable substances and sunlight.
Diagnosis is based on clinical evaluation of symptoms and the patient's history of exposure to vegetable substances and sunlight.
Treatment includes washing the affected skin with mild soap and water, applying cold compresses to reduce swelling and burning, and avoiding further sun exposure until the skin has fully recovered.
In more severe cases, topical corticosteroids or anti-inflammatory medications may be prescribed to reduce the skin reaction.
