Two female commercial hydrangea growers, from separate nurseries, presented with similar hand and facial dermatitis. Both had a hand dermatitis affecting particularly the first three fingers and backs of both hands and complained of a recurrent facial dermatitis affecting the forehead, around both the eyes and bridge of nose. They related their dermatitis to their work. Patch tests confirmed allergy to all components of hydrangeas including petal, leaf and stem. Avoidance resulted in resolution of their dermatoses. Allergy to hydrangeas has been reported previously although infrequently.
