Phytophotodermatitis caused by contact with a fig tree (Ficus carica)

Area of Science:

• Dermatology
• Botany
• Occupational Health

Background:

• Phytophotodermatitis is a skin reaction caused by contact with certain plants followed by exposure to ultraviolet (UV) light.
• Ficus carica, commonly known as the fig tree, contains photosensitizing compounds.
• Occupational exposure to Ficus carica sap can pose a risk for developing phytophotodermatitis.

Observation:

• Two arborists experienced acute blistering eruptions on their forearms, hands, and fingers after pruning a damaged Ficus carica tree.
• The affected skin showed erythema and bullae, developing after contact with the tree's sap and subsequent sun exposure.
• Symptoms resolved naturally within 4 to 6 weeks.

Findings:

• The clinical presentation and exposure history strongly suggest phytophotodermatitis induced by Ficus carica.
• The severity of the reaction highlights the potent photosensitizing nature of compounds within Ficus carica sap.
• Delayed recognition of this occupational hazard is common.

Implications:

• Increased awareness of Ficus carica-induced phytophotodermatitis is crucial for arborists, orchardists, and gardeners.
• Health professionals should consider phytophotodermatitis in the differential diagnosis of acute blistering eruptions in individuals with plant-related occupations.
• Preventive measures and education are needed to mitigate risks for horticultural and forestry workers.
