[Photodermatitis bullosa generalisata].
Two observed cases indicate atypical forms of phyto-photodermatitis (photodermatitis bullosa striata). Unusual localisations or generalised outbreaks have to be taken into account in cases of sunbathing without clothes on. Power lawn mowers with rotating blades spread heracleum and other phototoxic juices via freshly cut grass, causing diffuse - as opposed to striped - manifestations on the uncovered skin areas. The most certain prevention of such a reaction is to known which few plants are responsible for phyto-photodermatitis and to avoid them in sunny weather. The plants should by no means be exterminated, even those (such as Heracleum mantegazzianum, "giant hogweed") which have a tendency to spread.
