Unique Acute Phytophotodermatitis Reaction and a Visual Diagnostic Guide.

Here, we describe a case of a 48-year-old caucasian female with no significant past medical history who presented to the outpatient dermatology clinic with an extremely painful and significant phytophotodermatitis (PPD) reaction to over 30% of her body surface area. The patient presented after partaking in a ritualistic ceremony where she was exposed to plant and citrus juices and subsequently sunbathed while on a tropical vacation. While not an infrequent diagnosis, this patient presented to the dermatologist in extreme pain after having no education on avoiding such triggers. This diagnosis is relatively underdiagnosed and leads to a lack of patient counseling on the hazards of UV exposure secondary to contact with certain plant and fruit juices. Lack of patient awareness leads to an increase in disease burden. Furthermore, this patient suffered a large body surface area reaction in contrast to the pathognomonic description of phytophotodermatitis secondary to the exposure to lime juice which causes relatively less total body surface area exposure.

Phytophotodermatitis From Lime Margaritas on a Mexico Vacation.

Phytophotodermatitis is a type of contact dermatitis that occurs upon skin exposure to certain plant chemicals, known as furocoumarins, along with simultaneous sun exposure. This case details a 34-year-old patient who presented to the office with an asymptomatic, irregularly shaped, and hyperpigmented patch located on the left inferior middle back that had been present since a recent beach vacation in Mexico. Upon gathering the history, clinicians should inquire about recent sunlight exposure while consuming and/or touching phytotoxic plant derivatives found in most citrus plants. The history should correspond with the skin examination findings and conclude that a cutaneous phytotoxic reaction had occurred when a lime margarita contacted the hand, which was subsequently rubbed onto the patient's back. This case highlights the importance of both taking a thorough history and physical examination and being aware of the broad range of skin manifestations to prevent unnecessary treatment, such as topical corticosteroids, for other skin disorders (the irregular presentation of atopic dermatitis, allergic contact dermatitis, and dermatitis unspecified) or improperly suspected child abuse in younger patient presentations.

Phytophotodermatitis Due to Fig Tree Sap Activated by Ultraviolet Light: A Case Report.

Phytophotodermatitis is a dermatological reaction caused by exposure to certain plants, which becomes activated upon subsequent exposure to sunlight. This can frequently result in a rash. Typically, supportive treatment is recommended. In this report, we describe the case of phytophotodermatitis in a 57-year-old man who experienced a painful rash with streaked lesions following the pruning of a fig tree during the summer. The patient, with no significant medical history, presented to the emergency department in July with a painful, streaked rash on both forearms. The lesions appeared overnight, predominantly on areas of skin exposed while sleeping. The patient denied contact with potential irritants and had not engaged in recent travel or altered his usual habits. Laboratory tests, including complete blood count and markers of inflammation, showed no abnormalities. A thorough patient history revealed recent fig tree pruning, a task usually undertaken in winter. The diagnosis of phytophotodermatitis was made based on the characteristic skin lesions and the patient's history of exposure to fig tree sap. Treatment with antihistamines led to improvement in symptoms, and the patient was discharged with a week-long course of antihistamines and advice to avoid sunlight and contact with fig trees. This case underscores the importance of a detailed medical history, especially in the context of dermatological lesions, to accurately diagnose and treat conditions like phytophotodermatitis.

Fig Tree-Induced Phytophotodermatitis: A Case Report on the Perils of a Hobby.

Phytophotodermatitis, a condition that results from sequential skin exposure to phototoxic chemicals contained within plants, followed by exposure to solar ultraviolet radiation, has been described with several plants and plant-based foods, namely members of the Moraceaefamily, which include Ficus carica L. This tree's branches, leaves, and fruit skin exude a milky sap or latex containing proteolytic enzymes and furocoumarins known to be photoirritants, easily absorbed upon skin contact. Oxygen-dependent and independent toxic reactions subsequent to sun exposure promote cell membrane damage and oedema, consequently leading to cell death. The diagnosis is confirmed with a detailed anamnesis, and photopatch testing is often useful to rule out a differential diagnosis. It is typically a self-limited condition, with few cases requiring treatment with topical or systemic corticosteroids. We report on a 55-year-old male patient who, following picking figs and pruning a fig tree while exposed to sunlight, developed erythematous and pruritic maculopapular lesions that progressed to blisters with residual hyperpigmentation. The diagnosis was further corroborated through photopatch testing, and the patient was recommended to avoid this recreational activity without symptoms' relapse. This case highlights the importance of considering phytophotodermatitis as a differential diagnosis when evaluating cases of dermatitis on exposed body surfaces and the importance of an exhaustive anamnesis. Identification of specific plant triggers and the performance of photopatch tests are essential to help confirm the diagnosis and guide avoidance recommendations.

Phytophotodermatitis as a clinical problem and as a therapeutic option: Case report and review of the literature.

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.

Phytophotodermatitis due to a Citrus-Based Hand Sanitizer: A Case Report.

Phytophotodermatitis, a cutaneous reaction caused by direct contact with photosensitive substances in plants and subsequent exposure to ultraviolet light, is commonly caused by psoralens in plants, including citrus fruits. We describe a case of phytophotodermatitis caused by a hand sanitizer containing a blood orange (Citrus sinensis) extract. To our knowledge, this is the first reported case of phytophotodermatitis caused by a hand sanitizer. A 41-year-old woman presented with a 2-week history of pruritic cutaneous eruptions on her right thigh. Approximately 24 hours prior to the onset of her symptoms, she applied a new citrus-based hand sanitizer. Immediately after applying the hand sanitizer, her right thigh was exposed to sunlight for approximately 5 hours. Extracts from oranges are used in many cosmetics, including perfumes and fragrances. With the increased use of hand sanitizers during the coronavirus disease 2019 pandemic, physicians should note that phytophotodermatitis due to scented hand sanitizers may occur more frequently.

Recurrent Bilateral Lime Disease in a Young Female- Case Report.

INTRODUCTION: Lime phytodermatitis, also known as margarita dermatitis, is a condition that results in a skin rash after sunlight exposure when handling certain plants. Misdiagnosis is common due to its resemblance to skin burns or allergic contact dermatitis. Detailed history and disease recognition is important to provide accurate treatment recommendations. CASE REPORT: A 32-year-old woman presented with a recurrent rash on her hands that would only occur in the summer months. She was previously misdiagnosed as allergic contact dermatitis. History revealed yearly vacations involving margaritas and squeezing lime into her drinks followed by exposure to sunlight. A presumptive diagnosis of lime phytodermatitis was made and she was advised to avoid contact with limes followed by exposure to direct sunlight. DISCUSSION: Lime phytodermatitis occurs after direct contact with lime and sunlight exposure. A phototoxic compound found in limes, Furocoumarin, has been implicated as a cause for lime disease. Detailed history is important in establishing a diagnosis of lime disease. Treatment is symptomatic with topical corticosteroids, avoidance of furocoumarin-containing objects, cold compresses, and subsequent UV exposure. CONCLUSION: We present the first case of recurrent, bilateral phytodermatitis in a 32-year-old woman following contact with limes and subsequent sunlight exposure in the summer months.

Common Dermatologic Conditions in Returning Travelers.

PURPOSE OF REVIEW: Travel medicine practitioners often are confronted with returning travelers with dermatologic disorders that could be of infectious causes or inflammatory or allergic. Some dermatologic processes are the result of exposure to insects or acquired due to environmental exposures. There is a broad range of dermatosis of infectious and non-infectious etiologies that clinicians need to consider in the differential diagnosis of dermatosis in travelers. RECENT FINDINGS: With increasing international travel to tropical destinations, many individuals may be exposed to rickettsia (i.e., African tick bite fever, scrub typhus, or Mediterranean spotted fever), parasitic infections (i.e., cutaneous larva migrans, cutaneous leishmaniasis, African trypanosomiasis, or American trypanosomiasis), viral infections (i.e., measles or Zika virus infection), bacterial (i.e., Buruli ulcer) or ectoparasites (scabies or tungiasis), and myiasis. Cutaneous lesions provide clinical clues to the diagnosis of specific exposures during travel among returned travelers. SUMMARY: Dermatologic disorders represent the third most common health problem in returned travelers, after gastrointestinal and respiratory illness. Many of these conditions may pose a risk of severe complications if there is any delay in diagnosis. Therefore, clinicians caring for travelers need to become familiar with the most frequent infectious and non-infectious skin disorders in travelers.

Margarita Burn: Recognition and Treatment of Phytophotodermatitis.

Phytophotodermatitis is a cutaneous reaction caused by direct contact with phototoxic agents and subsequent sunlight exposure. Furocoumarins and psoralens are 2 phototoxic agents that can cause this reaction, and these organic chemical compounds are found in many plant species consumed by humans. Following contact exposure to such foods and ultraviolet radiation exposure via direct sunlight, phytophotodermatitis can occur. Due to the etiology of these rashes relating closely to the outdoor consumption of margaritas, the rash may be known by patients as "margarita burn." There is a classically described sequence of rash progression: erythematous macules or patches, which later become vesicles and seem similar to second-degree burns, followed by an asymptomatic hyperpigmentation. This case presents a 26-year-old female diagnosed with phytophotodermatitis following use of citrus fruits for margaritas while outdoors in direct sunlight. The diagnosis of phytophotodermatitis is often made clinically but can be complicated due to its similarity in appearance to many other common cutaneous reactions. In this patient, the differential diagnosis included solar erythema, contact dermatitis (type IV hypersensitivity reaction), polymorphic light eruption, or drug-related photosensitivity. Careful history taking is essential in not only narrowing down the differential diagnosis but also in avoiding unnecessary tests or ineffective treatments.

Babchi oil-induced phytophotodermatitis mimicking burn injury.

Babchi (Psorylea corylifolia) is occasionally used by patients as a herbal treatment in conditions such as psoriasis and vitiligo, due to its anti-inflammatory, anti-oxidant and immune-modulatory properties (Shrestha et al., 2018; Chopra et al., 2013). Due to its psoralen containing furocoumarins, it has the potential to induce photosensitive reactions. We present the first reported case of Babchi-induced phytophotodermatitis in the UK, presenting as sunburn.

Plant Associated Irritant & Allergic Contact Dermatitis (Phytodermatitis).

With more than 350,000 plant species recognized and new species continually being identified, it is not surprising that humans contact plants or plant-containing products daily. The nearly endless list of potential exposures leaves us with a challenging task when attempting to categorize and study potential plant-related irritants and allergens. This article focused on laying a sound framework for understanding some of the more pertinent potential irritants and allergens.

Clinical analysis of 11 patients with phytophotodermatitis caused by ingesting Chenopodium album / 中华皮肤科杂志

Objective@#To investigate clinical characteristics and treatment of phytophotodermatitis due to ingesting Chenopodium album.@*Methods@#This study included 11 patients with phytophotodermatitis caused by ingesting Chenopodium album collected from Department of Dermatology, Affiliated Hospital of Jining Medical University from 2013 to 2017. The patients′ general information, clinical manifestations, laboratory test results, treatment and prognosis were retrospectively analyzed.@*Results@#All the 11 patients were female, and their age ranged from 45 to 62 years. They all had a history of ingesting Chenopodium album and exposing to sunlight within 1 - 2 days prior to the disease onset. Clinical manifestations included symmetrically distributed, painful and pruritic, nonpitting, swelling erythema on the face and back of both hands and at sunexposed sites of forearms, with a tense and bright surface. Increased white blood cell counts were observed in 6 patients, and increased eosinophil counts in 1. All of the 11 patients were treated with systemic methylprednisolone, loratadine, ebastine, spironolactone, furosemide and omeprazole as well as topical agents, 2 also received human immunoglobulin treatment, and 3 were also treated with oral ibuprofen and codeine for painful lesions. Ten patients received obvious improvement and were discharged after 7 - 10 days of treatment, and no pigmentation or scars were observed after 1-year follow-up. Skin necrosis occurred on the back of both hands in 1 patient after 7-day treatment, and scars remained in the patient after follow-up of half a year.@*Conclusions@#Chenopodium album-induced phytophotodermatitis commonly manifests as swelling erythema on the exposed body sites. After confirmed diagnosis, Chenopodium album ingestation and sunlight exposure should be avoided, and timely antianaphylactic treatment should be considered to effectively control the disease.
