Area of Science:

  • Occupational dermatology
  • Allergology
  • Wood chemistry

Background:

  • Occupational exposure to wood products can cause allergic contact dermatitis.
  • Pine wood is a common material in various industries.
  • Chemical treatments of wood may alter its allergenic potential.

Observation:

  • A 34-year-old woman presented with dermatitis on exposed areas (arms, face, neck).
  • The patient worked with pine wood treated with sodium hydroxide and pyrogallol.
  • Symptoms developed following occupational exposure to the treated pine wood.

Findings:

  • Patch testing revealed specific allergic reactions to colophony and pine wood.
  • No allergic reaction was observed for sodium hydroxide or pyrogallol.
  • Colophony, a known allergen, is a natural component of pine wood.

Implications:

  • Identifies colophony in pine wood as the causative agent for allergic contact dermatitis in this case.
  • Highlights the importance of accurate patch testing for diagnosing occupational dermatitis.
  • Demonstrates the effectiveness of allergen avoidance in managing occupational skin diseases.
