[Phototoxic contact phytodermatitis: clinical and biological aspects].

We report the case of a 39-year-old patient, gardener, who develops, during a beautiful sunny summerday, an erythemato-bullous eruption of the forearms. The diagnosis is a Contact Phototoxic Phytodermatitis (dermite des prés, dermatitis bullosa striata) with a classical presentation. This clinical observation gives us the opportunity to remind of the clinical and biological aspects of this dermatosis, whose frequency is probably underestimated, related to an often rapidly favourable evolution.
