Abstract:
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.
