Background: Phytophotodermatitis is a contact photodermatitis to furocoumarins, which act as sensitizing psoralens, from certain plants, especially citrus and fig trees. This photosensitizing effect has traditionally been used for the treatment of cutaneous viral warts, a reflection of traditional medicine. However, there are hardly any studies that support this fact. Otherwise, on certain occasions, especially in extensive exposures, they can cause a generalized severe condition that can even put the patient's life at risk.
Case presentation: We report the case of a 28-year-old man with severe phytophotodermatitis after generalized photoexposure with the manipulation of a fig tree, which required hospital management in a burn unit.
Results: A traditional method for the treatment of warts in some rural areas, especially in Iran, comprises the use of fig tree (ficus carica) latex as a local treatment; however, there is no scientific evaluation of its efficacy. It bases its effectiveness on physical destruction due to the sensitizing effect of furocoumarins. Though, in generalized exposures of this tree, as the case of our patient, can cause fatal symptoms. The essential therapeutic pillar is the avoidance of exposure to this tree and of sun exposure. Symptomatically, topical corticosteroids and systemic antihistamines are used. In severe cases, admission to a burn unit may be necessary.
Conclusion: In conclusion, we highlight the importance the importance of early detection of phytophotodermatitis, an entity that can be caused by the daily handling of trees, including fig trees, a traditional remedy for viral warts and which, without adequate supervision in its application, can cause severe generalized symptoms.
