The plant was id entified as Euphorbia helioscopia L. (sun spurge). The sun spurge belongs to the Euphorbiaceae plant family. These plants produce a typical milky juice that cau ses toxic reactions following contact with skin and mucous membranes. In the lit erature several cases of toxic dermatitis caused by plants of the Euphorbiaeae f amily have been described. The most important differential diagnosis of these sk in lesions is the bullous phototoxic dermatitis caused by psoralens. Plant-induced toxic dermat itis is of increasing importance in dermatology. The exact determination of the causative plants is a prerequisite for the diagnosis of phytodermatitis.展开更多
