Contact Dermatitis From Exposure to Virginia Creeper (Parthenocissus quinquefolia): A Deviation From the Saying "Leaves of Three, Let It Be".

Phytodermatitis is often caused by contact with certain plants and may be recognized by the common saying, However, lesser-known plants, such as Virginia creeper (), can also cause significant contact dermatitis (CD). A 54-year-old female physician with a history of poison ivy allergy presented with a pruritic, erythematous, blistering rash with linear streaks on her face, neck, and arms following exposure to Virginia creeper plants in her backyard. Symptoms began 48 hours post-exposure, exhibiting linear streaks and scattered plaques suggestive of allergic contact dermatitis (ACD). The patient self-treated with topical betamethasone, diphenhydramine, ibuprofen, and petroleum jelly. Symptoms significantly improved within one week, with complete resolution by one month. Removal of Virginia creeper plants from her backyard prevented further recurrence. Clinicians and the public should be aware that Virginia creeper, despite its five-leaf configuration, can cause phytodermatitis that is very similar to poison ivy. Recognition and identification of plant-induced dermatitis are significant for effective management and prevention.
