title: Bulb dermatitis. Dermatological problems in the flower bulb industries.
abstract: The irritant and allergenic properties of the most important flower bulbs are described, as well as the clinical symptoms they cause. The tulip contains the allergen tulipalin A; sensitization and irritation are responsible for the development of tulip fingers. The same clinical picture can be caused by Alliums like the onion and garlic. The narcissus causes lily rash, a dermatitis rarely caused by sensitization. The hyacinth evokes itching in practically everyone: an irritant reaction caused by calcium oxalate crystals. Patch testing is complicated as the allergens are not all identified.
