Phytophotodermatitis, a form of plant dermatitis, is a common phototoxic reaction resulting from the interaction between photosensitising botanical substances present in several common plant families and ultraviolet radiation. We report a case of phytophotodermatitis in an 8-month-old infant who presented a progressively well-demarcated erythematous rash with blisters and subsequent erosions covering both upper limbs and feet. Additionally, asymmetric hyperpigmented streaks with bizarre configurations, were observerd in photo-exposed areas. The diagnosis of phytophotodermatitis was established based on the history of outdoor activities with sun exposure and physical examination findings. Topical treatment with antibiotic and corticosteroid cream was started. The phytophotodermatitis is a self-limiting condition, which can be challenging to diagnosis in this age group due to heterogeneity of clinical manifestations, which can mimic a range of different diseases, such as non-accidental injury in the context of child abuse, potentially delaying timely diagnosis and treatment.
