Occupational Contact Dermatitis Due to Codiaeum Variegatum L., Chrysanthemum indicum L., Chrysanthemum x hortorum and Frullania dilatata L.
This report describes a case of contact eczema in a driver-deliverer of plants and flowers. The evolution of his dermatitis was closely connected with this work. Patch tests showed positive reactions to Codiaeum variegatum (L.) A.Juss.var. pictum (Lodd.) Müll. Arg., cultivars Excellent, Mrs Iceton and Norma, to Chrysanthemum indicum L., Chrysanthemum x hortorum, Frullania dilatata L. and to balsam of Peru. Patch test results were also positive to water, methanol and ethyl acetate extracts of the leaves of the cultivar Excellent but negative to a hexane extract. Therefore, hypersensitivity included some plants that belong to three different families : Euphorbiaceae, Compositae and Hepaticae. Contact allergy to Chrysanthemum and to Frullania is well known. A few cases of allergic contact dermatitis due to Codiaeum variegatum have been described in the literature. This plant, often called florists croton, should not be confused with Croton tiglium L., or croton oil plant, which is a strong irritant to the skin. This case focused our attention on the difficulty of skin protection and the serious problem concerning the patient’s occupational future.
