Phytophotodermatitis results when skin is exposed to ultraviolet light after previous contact with a phototoxic compound. Wild parsnip (Pastinia sativa), a member of the Umbelliferae family, is an invasive plant species introduced to North America as a root vegetable. Although cultivated less commonly today, the plant is increasingly found growing wild in prairies and roadsides. The stems and leaves contain furocoumarins, which upon activation by UV light interact with oxygen. Resultant reactive oxygen species induce tissue damage manifesting initially as blistering and later as hyperpigmentation...

Phytophotodermatitis is a clinical diagnosis from phototoxicity of the skin induced by contact with plants or their extracts. Phytophotodermatitis maypresent with burning, erythema, patches, plaques, vesicles, bullae, or hyperpigmented patches in welldemarcated and unusual shapes. Inquiring about occupation, hobbies, and plant or plant extract contact is essential to establishing the diagnosis. Herein we present a case of phytophotodermatitisafter use of carrot extract-containing sunscreen presenting as a hyperpigmented patch in a geometric distribution with accentuation of pigment within the dynamic rhytides...

Phytophotodermatitis is a condition that occurs by contact with plants containing phototoxic agents such as furocoumarins and psoralens with subsequent ultraviolet exposure. Phytophotodermatitis typically presents as sharply defined erythematous patches with occasional blistering, sometimes accompanied with pain or itching sensation. In some cases, however, sudden appearance of asymptomatic hyperpigmentation can be the only clinical finding of phytophotodermatitis. Here, we present two patients with sudden development of asymptomatic pigmentation on their hand without preceding inflammation by the contact with citrus fruits containing photosensitizers and subsequent exposure to strong sunlight...

INTRODUCTION: Phytophototoxic dermatitis is a strong phototoxic reaction to ultraviolet A (UV-A) radiation exposure after cutaneous contact with citrus fruit containing furocoumarins, leading to skin injury. At the Arizona Burn Center (Phoenix, AZ), the majority of these injuries are managed in the outpatient setting. CASE REPORT: The authors present a pediatric admission for burn-like injuries following prolonged cutaneous exposure to lemons while playing in the Arizona sunshine...

Phytophotodermatitis is a condition caused by sequential exposure to photosensitizing substances present in plants followed by ultraviolet light. Several plants (e.g., limes, celery, fig, and wild parsnip) contain furocoumarin compounds (psoralens). It is important for dermatologists to be aware of phytophotodermatitis because it may be misdiagnosed as cellulitis, tinea, or allergic contact dermatitis. We present five patients with a sharply defined erythematous swollen patch with bullae on both feet. They described soaking their feet in a fig leaves decoction to treat their underlying dermatologic diseases...

Phytophotodermatitis is almost exclusively reported in the dermatological literature, but may progress to a chemical burn. There has been widespread media reporting during the summer of 2015 of burns caused by giant hogweed. However, there is a lack of awareness of this mechanism of injury amongst the burn multidisciplinary team, and there have been no published articles in the surgical literature regarding plant burns, other than sporadic case reports, for 20 years. We present a comprehensive review of plant burns and three cases from our adult and paediatric Burn Centres of burns caused by giant hogweed...

A 3-year-old girl presented with a linear eruption on her leg for 2 months. She was otherwise healthy and well-appearing. Physical examination showed many small, erythematous, flat-topped papules coalescing into a linear erythematous plaque. At a follow-up visit 9 months later, the eruption had resolved, leaving postinflammatory hypopigmentation.When approaching a cutaneous eruption, appreciating the pattern of the lesions can be instrumental to arriving at the correct diagnosis. For this patient with the acute onset of a plaque on the leg, the differential diagnosis is narrowed by the linear distribution of the skin lesions...

BACKGROUND: The cutaneous manifestations of pathological conditions have been described to mirror findings commonly associated with child abuse. Although it is important for clinicians to report suspected abuse, vigilance is required to detect conditions that mimic abuse. Phytophotodermatitis, a phototoxic reaction to furocoumarin-containing plants, is a well-described mimicker of nonaccidental trauma. However, non-furocoumarin-containing chemicals may cause similar presentations through a process called auto-oxidation...

BACKGROUND: Although the oleander plant is practically ubiquitous throughout the Mediterranean area, very few publications refer to its cutaneous toxicity. PATIENTS AND METHODS: Herein, we report two cases of irritant contact dermatitis caused by oleander. The patients in question were twins who had oleander leaves applied directly to their face for 20minutes. The initial lesions consisted of periorbital erythema, followed by the emergence of papules and macules...
