RESUMO
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.

Erythema multiforme is a skin disorder characterised by target epithelial eruption, which is mainly caused by infection or drugs. In this case, we report an erythema multiforme like reaction caused by contact dermatitis against wood, especially santos rosewood. During the hospitalisation, we performed a patch test with lumber used in the patient's workplace, and recognised a positive response to multiple woods and a simultaneous recurring eruption (flare up) outside of the test site. The findings from this case of contact dermatitis caused by frequently used industrial wood type is important for the management of occupational environments. A review of the literature on erythema multiforme like reaction due to contact dermatitis, including past case reports, has also been provided.

Allergic contact dermatitis is a common skin disease, which affects approximately 20% of the population. This reaction may present with several clinical manifestations. Erythema multiforme-like allergic contact dermatitis is a rare type of non-eczematous contact dermatitis, which may lead to difficulty in diagnosis.Essential oil of Laurus nobilis is widely used in massage therapy for antiinflammatory and analgesic effects. Laurus nobilis induced contact dermatitis has been reported in the literature but an erythema multiforme-like presentation is rare.

Exposure to plants is very common, through leisure or professional activity. In addition, plant products and botanic extracts are increasingly present in the environment. Cutaneous adverse reactions to plants and their derivatives occur fairly frequently, and establishing the correct diagnosis is not always easy. The astute clinician relies on a detailed history and a careful skin examination to substantiate his opinion. This article reviews the characteristic clinical patterns of phyto- and phytophotodermatitis and some less common presentations.

This study reports a case of localized contact dermatitis and subsequently generalized erythema multiforme-like eruptions after topical application of herbal remedies. Patch tests showed there was an allergen in fresh and dried Alpinia galanga, which is also a popular spice in Southeast Asian cuisines.

We report two patients in whom episodes of polymorphic light eruption were followed by recurrent erythema multiforme on exposed and nonexposed sites. Treating the polymorphic light eruption with prophylactic PUVA and/or oral prednisolone or cyclosporin prevented the development of erythema multiforme, suggesting that the two events are related. It is possible that erythema multiforme develops as a response to the same causative antigen as polymorphic light eruption.

Erythema multiforme (EM) as a complication of patch testing (PT) is rare. A 52-year-old woman with a 13-year history of episodes of EM, after contact with weeds during home gardening, had had no recent history of herpes simplex, other infection, drug ingestion or vaccination. On examination, EM lesions were distributed on the exposed skin. 5 weeks after complete resolution, PT and photopatch testing (PPT) were done with fresh plants she brought in. She was PT with a standard series and the Hermal-Trolab plants, woods, tars, balsams and flavors series. Intradermal testing, with a 3 + reaction to mixed weed pollens, was done 3 weeks later. Specific IgE to weed pollens class 1 (CAP-Pharmacia) was detected. Eczematous PT reactions were obtained with fresh leaves: common chickweed (Stellaria media Caryophyllaceae), dandelion (Taraxacum officinale Compositae), field-milk thistle (Sonchus arvensis Compositae) and white clover (Trifolium repens Leguminosae). Photoaggravation was seen to common chickweed and dandelion. Positive PT was also seen with alantolactone. By the 4-day reading, a typical EM had commenced, coming up to quite the same extent as seen on admission. There was no photosensitivity (UV skin tester, K. Waldmann). In the essential oil obtained from common chickweed, thin layer chromatography (TLC) revealed the well-known contact allergens borneol, menthol, linalool, 1,8-cineole, and other terpenes such as epoxy-dehydro-caryophyllene, monoterpene alcohol-ester and caryophyllene. Up to now, no data on essential oil in Stellaria media (common chickweed) have been reported. It can be concluded that EM developed due to contact with weeds, and recurred after patch testing. Neither blistering nor eczematous lesions have been seen on her skin, making this case very unusual. As far as the world literature is concerned, this is only the 4th report of EM developing in association with patch testing.
