Commercial hydrangea growers can develop allergic contact dermatitis from handling the plant. Patch testing confirmed allergies to hydrangea petals, leaves, and stems, leading to hand and facial skin issues.

Area of Science:

  • Dermatology
  • Occupational Health
  • Allergology

Background:

  • Occupational contact dermatitis is a common concern in horticultural professions.
  • Previous reports of hydrangea allergy exist but are infrequent.

Observation:

  • Two female commercial hydrangea growers presented with distinct hand and facial dermatitis.
  • Symptoms included hand dermatitis on fingers and backs of hands, and facial dermatitis on the forehead and around the eyes.
  • Both growers linked their symptoms to occupational exposure to hydrangeas.

Findings:

  • Patch testing confirmed allergic contact dermatitis to all parts of the hydrangea plant (petal, leaf, stem).
  • Complete avoidance of hydrangea exposure led to the resolution of their dermatoses.

Implications:

  • This study highlights hydrangeas as a potential occupational allergen in horticulture.
  • Awareness and diagnostic testing are crucial for managing plant-induced contact dermatitis in growers.
  • Further investigation into the specific allergens within hydrangeas may be warranted.
