Severe phytophotodermatitis from fig sap: a little known phenomenon.

Area of Science:

• Dermatology
• Toxicology

Background:

• Phytophotodermatitis is a skin reaction caused by contact with certain plant compounds followed by exposure to ultraviolet (UV) radiation.
• Common culprits include citrus fruits, celery, and figs, often encountered during outdoor activities.

Observation:

• A 46-year-old arborist presented with a severe, blistering rash on his arms and neck after pruning a fig tree.
• The rash appeared two days after sun exposure to fig sap, accompanied by pain and swelling.
• Initial self-treatment with aloe vera and wet wraps was ineffective.

Findings:

• Clinical diagnosis of phytophotodermatitis was confirmed.
• The patient's forearms showed significant erythema and blistering consistent with this condition.
• No secondary infection was noted on examination.

Implications:

• This case underscores the importance of recognizing phytophotodermatitis in individuals with occupational or recreational sun exposure after plant contact.
• Awareness of potential triggers like fig sap is crucial for prevention.
• Prompt diagnosis and management, including wound care and antibiotics if indicated, lead to good outcomes without long-term sequelae.
