Implication

A case report demonstrates sensitization and tolerance in a woodworker exposed to Thespesia populnea.

Key Points

  • To investigate the sensitizing capacity of constituents from Thespesia populnea wood in a patient with allergic contact dermatitis.
  • Extracted wood shavings and isolated compounds
  • Conducted patch tests with sawdust and isolated main compound
  • Performed sensitizing experiments in guinea pigs
  • Patch tests initially yielded positive reactions to wood constituents
  • The patient developed tolerance over time to the sensitizer
  • Identified the main component as a new mansonone with moderate sensitizing capacity
