Two cases of cutaneous hepatic porphyria of toxin origin were identified within a small period of time. Both patients are farmers and recently handled very intensively, without any precaution, some pesticides containing organo-phosphorated substances. Due to its toxic character the disease is similar with the so called Turkish porphyria. It is to be remarked: 1. The professional nature of the disease. 2. The up to now unreported reference of the induction of cutaneous porphyria by phosphorated agents.
