A case report was presented of man in whom exposure to the spathe flower (Spathiphyllum-wallisii) caused allergic rhinitis, laryngitis, pharyngitis, contact urticaria, and generalized urticaria. The 22 year old man worked for a firm that rented plants to businesses and also maintained the plants. He had exceptionally strong occupational exposure to plants because he washed, cleaned and trimmed them. On the job he had mild respiratory symptoms that development into an asthmatic condition. Spathe flower and dracena gave positive responses in skin prick tests. The authors conclude that the patient probably developed direct respiratory symptoms from respiratory exposure to the plant allergens, and contact dermatitis/urticaria from skin contact with plant allergens.
