Summary
Severe allergic contact dermatitis in children was caused by the Japanese lacquer tree (Rhus verniciflua). Delayed diagnosis is common for non-native plant allergies, often misdiagnosed as cellulitis.
Area of Science:
- Dermatology
- Toxicology
- Botany
Background:
- Allergic contact dermatitis (ACD) is an immune response to allergens.
- Plant-induced ACD can be challenging to diagnose, especially with non-indigenous species.
- Rhus verniciflua, the Japanese lacquer tree, is a rare plant in the UK.
Observation:
- Three paediatric cases of severe ACD are presented.
- Patients experienced reactions after exposure to Rhus verniciflua.
- Clinical presentation mimicked other skin conditions.
Findings:
- Rhus verniciflua was identified as the causative agent of ACD.
- Delayed diagnosis occurred in these paediatric cases.
- Misdiagnosis as cellulitis was noted.
Implications:
- Highlights the potential for severe ACD from rare, non-native plants.
- Emphasizes the need for increased awareness among clinicians.
- Suggests considering ACD in paediatric patients with unexplained dermatitis, even with unusual exposures.
