Late patch test reaction to acrylates in a dental worker
1Division of Dermatology, University of Louisville School of Medicine, Louisville, KY, USA.
Summary
A dental technician experienced allergic contact dermatitis from acrylic nail products. Delayed patch testing confirmed a true allergy to ethyl acrylate and methyl methacrylate, not active sensitization.
Area of Science:
- Dermatology
- Allergology
- Occupational Health
Background:
- Dental technicians can be exposed to various chemicals, including acrylics used in nail products.
- Allergic contact dermatitis is a common occupational hazard in professions involving chemical exposure.
Observation:
- A dental technician presented with eyelid and hand dermatitis.
- Previous patch testing with an acrylic nail product showed a delayed positive reaction after one month.
Findings:
- Repeat patch testing with ethyl acrylate and methyl methacrylate elicited a delayed positive reaction, evident after five weeks.
- The delayed hypersensitivity reaction suggests a true allergic manifestation rather than active sensitization.
Implications:
- This case highlights the importance of considering delayed hypersensitivity reactions in patch testing for occupational dermatitis.
- Awareness of potential allergens like ethyl acrylate and methyl methacrylate is crucial for preventing and managing allergic contact dermatitis in dental professionals and nail salon workers.
