Title Allergic contact dermatitis from hydrangea - Is it so rare?
Bibliographic information Oct. 2000, Vol.43, No.4, p.189-191. 15 ref.
Abstract Eight cases of allergic contact dermatitis from the ornamental plant Hydrangea macrophylla observed in Angers, France, during a period of 15 years are reported and compared to other cases described in literature. Allergic contact dermatitis from hydrangeas appears to be an occupational dermatosis among nursery workers, presenting as a chronic eczema involving the hands and especially the first 3 fingers. Differential diagnosis from irritant contact dermatitis may be difficult. Patch tests with the stem as well as the leaf of hydrangeas gave strong positive reactions in all patients, and hydrangenol, the allergen of hydrangea, when tested, always also gave a positive reaction. Sensitization seems to occur after prolonged contact with the plant, which could explain the relative frequency in Angers, a city that provides almost 90% of hydrangea seedling production in France.
